6 parts with the seals that can go in different order and direction. Still was leaking when assembled correctly. Difficult to disassemble to clean. Other brands have 3 parts and intuitive assembly order.

Like I said, it's better than the hard spout cups but it still isn't great. The top does have a lot of pieces but they are big and easy to clean and assemble once you know how. It does leak a little if you flip it upside down. My problem is my child who always leaves her cups upside down on the beds, which in the case of this cup means the valve gets left open and all the liquid spills out. I also didn't realize when I bought these that the tops would not fit on the other avent bottles we already have.

The cup looks nice and I like the lid, but there are too many parts. When my child drinks from the cup, it gets all over him and releases too much milk too quickly. It's hard to tell if there is a right or wrong direction for the seal, I've tried both directions and get the same result. Also, I wish the handles were optional and could be removed when the child gets older. I'm disappointed that it makes almost as much mess as drinking from a regular glass.

Even after a youtube video, I could not see my way to putting this together. Much easier to use the sippy cups with valves that I used for my first grandchild. One should not have to spend that much time trying to assemble a cup.

I liked the cup. I bought 18 months one. My daughter started drinking by herself immediately I filled water in it. It's easy to use and water is not spilling out it's great thing but it's lead is very difficult to close.

All this cup did was leak all over. I would not recommend this cup to any body

I brought this cup for my one year old son. After a few months the cup began to leak every where. Today my son was drinking from it when I noticed that there was black stuff floating in his cup. The cup had mold. Please redisgn this cup because it can make kids sick

I bought this for my son hope he will learn to drink out of the cup like adults, but the water leaked on his shirt. And the top is not easy to clean. It's all black inside the top.

Received these avent fast flow nipples as a free sample. They work really well. The milk came out at the right pace for my son.

I was given this product for free in exchange for my review. This nipple was no different than all the other nipples out there. I am not sure that a baby needs to get food faster than what the 3 provides. I can`t say that I plan to use these in the future, I like the pace of the 3.

I received this as a free tester to test the product with my one year old. I liked it as far as easy to clean, easy to use, easy to take on and off. My son didn`t love it but i think its more because it is a much wider nipple than he was used to using on his bottle the past year. I would recommend it highly.

This nipple works great for my baby. It also doesn't interfere with breastfeeding which is great. No problems latching going back and forth from breast to bottle. The flow is very good and what makes them even better is that they are BPA free! They are also easy to clean and my baby loves them. I got these as a free sample and I will definitely be purchasing more!

I received these nipples as a free sample to try, and I loved them!! At first I was concerned that they would be too slow for my little one, but there was no complaining on his part. He seemed happy and he was not taking in any extra air. I can see myself purchasing more of these nipples.

I should start off by saying that every baby is truly different in their preference in bottle nipples. I received this product as a sample for my partially breastfed 5 month old child. Unfortunately she did not accept/like these nipples as I would have thought she would. She is more breastfed than she is bottle fed and these nipples are skinny and long and probably don`t mimic the actual breast nipple (or at least mine). I have 5 children in total-- 2 out of the 5 were exclusively bottle fed and this brand of nipple/bottle was their favorite. In my opinion this nipple is great for babies who are bottle-fed and not for transitioning breastfed babies...but it really depends on your baby`s preference.

I received the fast flow nipples as a free sample for my Avent bottles. We switched to this size after a few months when it seemed like my daughter was taking in a lot of air and I have to say these made a huge difference. This allowed for the liquid to come out faster and I felt that she was more comfortable and we had less burping as she didn't swallow as much air. I wish I tried these sooner!

I received these fast flow nipples as free samples to review, and overall they work well. They allowed my baby to get the right amount of milk for what he's been used to. At times, I thought that they were a little slow, but my little guy didn't seem to fuss over it. I love that they are BPA free!

I received this as a free sample from Philips. I loved the bottles but my 2 year old was complaining the nipples that came with the bottles were too slow. So I was ecstatic to try these nipples with my daughter and she loved it. She rarely takes a bottle and only uses Avent. The nipple flow was perfect and it did not leak. I purchased another box after my free sample.

Happy to have received this as a free sample to try out before buying myself! The nipple is nice and soft for breast-fed baby. They flattened easily in my baby's mouth mimicking my nipple and was easy for her to go back and forth between my breast and this nipple. Unfortunately, I had a hard time cleaning the nipple. The grooves near the hole trapped soap bubbles that were hard to remove even with the nipple end of my bottle brush. I can see how the grooves help milk flow to the baby's mouth, but I'm concerned that soap may be getting stuck in there. Overall, these nipples are good. They have a nice sturdy feel and are BPA free. I may try to find ones that don't have those grooves in the top though! In return for my review, I was given the above mentioned product for free. The impressions stated are 100% my own.

Loved this product. I must add that I was sent this product for free to review

I received these as a free sample along with a 3-pack of bottles. These are all fine and good, but why in the world would you sell a two-pack of nipples along with 3-packs of bottles? Baffling.

This product was received as a free sample for purpose of a review. This product was used for my 5 month old child. The nipples are good quality. The flow seems normal to any other product out there. The was no leaking and they are easy to clean. With new teeth my child wanted to chew on the nipple. There were no marks left behind and she seemed over all pleased with the ease of using it. Overall I would recommend these nipples to other parents.

easy to use .my baby likes this nipples very much.

Free sample in hand and went right to work....my big guy, 13mo, was very happy with the nipple shape and the ability to eat FASTER! Didn't notice him burping too much (no extra gas/air) so this mommy was very happy

The nipple worked well. Our baby is not particularly picky when it comes to nipples. This nipple is quite firm and firmer than some of the other brands we`ve tried. This is good because it didn`t invert or require adjustment. There wasn`t any leakage. We'll probably also try the wide version of this nipple. I should mention that I was sent a free sample to use for this truly honest review.

I received the fast flow nipples as a free sample for my Avent bottles. My daughter is a fast eater, so the fast flow nipples were great for her and resulted in her sucking much less air while eating. The fast flow nipples do allow the liquid to come out pretty quickly, so they are best for older, faster bottle-eaters.

I bought a pair of these or my twins. They work great & really don't leak. My girls could use them easily by about 18mos, maybe a bit earlier. Just for kicks, within a few days of getting the cups, both girls figured out how to press the edge of the cup & dump them out. They never used spout cups, but like the straws & this was a great way to ease them into regular cups. Unfortunately, I accidentally melted them & it's been so much less expensive to replace them with the straw cups that I haven't gotten more yet.

I have bought the munchkin miracle cup and this cup and if it weren't for the price I would buy a ton more because its much more durable than the munchkin cuo and it doesn't spill. I have used this cup over a month and its still intact and my daughter loves it! The munchkin cuo has a ring around it and it tore which made it began to leak and this cup doesn't have that. I've always loved avent products and will definitely keep buying from them :)

This cup was recommended to us by our pediatrician for our daughter that was having trouble sucking out of traditional sippy cups. We tried it and loved it, worked great for her! We went out and bought several more we liked it so much. Unfortunately after the first month or so they have all become useless. They will not stay assembled and the bottom 2 pieces of the lid continually fall into her drink while she is trying to use the cup.

My 11mo old son couldn't figure out sippy cups and loved drinking straight from an adult cup, but alas the spills were a problem, even with me holding the cup. I was convinced he would be drinking from a bottle till 18 mo plus. Enter this cup -- it is a perfect solution! He figured it out on the first try, and the only time it leaks is when he gets a mouthful and doesn't swallow. For those who say it leaks, yea, it does leak, but only when it isn't properly assembled; otherwise, I can tip it, turn it over, shake it, with no leaks. Liquid escapes only when the top is depressed. Then, its up to your child to swallow in time so it doesn't go all over him/her. The included instructions were easy to understand and it is easy to reassemble after washing. Love it!! Thank you for this design!

This cup leaks all over the place! I have tried reassembling and to no avail- my son has fun splashing in the puddles this cup makes. Good concept- but the cheap brands work better! Disappointed in this avent product!

My daughter's drink runs down her mouth and neck. The concept is great just didn't work for me. Avent should redesign this cup to work better.

Thought this was going to be spill proof as stated but leaks all over the place. May as well gave him an actual cup to drink out of. Loved using Avent bottles but this sippy cup is of no comparable value to their bottles.

My 2 year old got into the sippy cup drawer and wanted this cup. Oh boy. We can't figure it out. Once I watched a video on assembling it, but I don't know where I ever found it. I tried using the assembly illustration here (that's why I'm on this site right now), and it just doesn't go back together the way I remember it going originally. It was relatively spill proof, but now I've got it assembled as illustrated, and it's definitely not going to be spill proof. We are potty training right now, so having his beverage on the floor is not the worst thing I'll ever encounter today. That said I am disappointed. I loved this cup the first few times we used it. It went through the dishwasher assembled and it wasn't until I realized that people weren't disassembling to wash it that I learned it is near impossible for my husband and I to assemble. Thanks if you can point me in the directions of a tutorial that will allow us to use this cup.

Leaks everywhere. My daughter loves this cup but more ends up on the floor than in her mouth.

I did not find this cup easy to assemble. I took it apart 4-5 times before I ever put milk in it. When I finally put in milk and thought everything was good, I realized that I needed to work a bit harder. I did get it to the point of being leakproof ΓΒΆΓΆΒ¬" until my 16 month old figured out that she can get it to spill milk all over the table if she lays it on its side and presses the top. I imagine that it will be great at about two, but twelve months is too young of a recommendation in my opinion. We have to watch her like a hawk when she uses this cup.

Is most definitely NOT spill proof, my daughter carries it around the house and spells her liquid everywhere!! She hates it, I hate it, I wish my husband would have never bought it. So, thank you for your broken promises of a spill proof cup that helps them learn how to use a regular cup. You have severely ruined my day and my daughters day.

I am a first time mom with a picky son, when he was six months our pediatrician recommended I transition to a sippy cup but he refused to drink out of hard spout sippy cups and wanted to drink out if a big kid cup, so I went looking and found several leaky soft spout cups and this rather pricey cup, I purchased this cup and use it at mealtime, my son at six months could use it and at one year he can drink out if a big kid cup with ease, although during travel or if I want to prevent spills since he is in the throwing stage, I still will use this cup if I am not immediately with him throuout meals! Best money I ever speant and totally worth it! The cup doesn't leak and is just as easy to use as a standard cup without the spill risk!

I feel like I wasted my money as you can't use it for juice which is my greatgranddaughter prefers. Won't recommend it and sure won't buy any more.
