I purchased our seat in March of this year, 2016, and have sat closer to the steering wheel to ensure the seat doesn't touch. I drive a two door Honda Accord and the Diono Rainer sits in the middle in the back seat, rear facing with my toddler. Yesterday i picked up the angle adjuster and having the extra room to tilt my driver seat back is greatly appreciated. I ordered the dry seat too since potty training is around the corner. Braeden is unsure of the change in his foot space. It is not a severe change for his legs and definetly still has more leg room than other rear facing seats, so we will see if he adjusts. It is better all around to have this pad under his seat.

We use this for my 2.5 year old RFing and will be ordering one next month for my almost 9 month old now that she meets the requirements! :)

We got our Radian once our LO grew out of his 22lb limit infant seat. We had to purchase the Angle Adjuster in order for the Radian to even remotely fit in our 2010 Toyota Highlander. It works. It does make installing the car seat take a little more time. And the foam does flatten over time in the front from pressure. It does what it is sold to to, and we appreciate that.

I bought two months ago and it is comfortable a lot

This product does indeed make the seat sit more upright while rear-facing. However, the foam compress within 2-3 months so much that the upright factor goes away and I have to buy yet another one for my extended rear-facing children. I have gone through at least 4 already in 2 years (I don't buy new ones right away because it's a pain and it adds up). Also, on leather seats the foam slides around making a tight install that much more difficult. Please, redesign your seats. I bought two of them because of their ratings but between trying to get a good installation rear-facing, the angle issue and the headwings always sliding down, I'm very frustrated.

We have the Diono Radian RXT for our daughter and she was so excited when we added the Angle Adjuster. She can now sit more upright (which at over a year old she definitely prefers) and we have more room in the front seat. We plan on keeping our daughter rear facing as long as possible and with the addition of the Angle Adjuster she is much more content in the car and probably feels more like a big girl because it is easier for her to look around and see what's going on now that she is not laying down so much like she was before we got the Angle Adjuster. I also feel safe knowing that since it is made by the same company that made our car seat it was designed and tested to be a safe combination with our Diono carseat.

This adjuster was perfect to tilt the carseat a bit more vertical to avoid drivers seat. Even though it is "just a piece of foam" I would still recommend buying the Diono brand.
