Sturdy Car Seat
May 13, 2013
Love this car seat and I love that this one works up to a larger weight limit of 70lbs. However, my Marathon which has a weight up to 65lbs for my other child has small velcro strips on the sides on the car seat which hold back the straps when the child gets in. This Marathon does not have this feature, I miss them. I would recommend they bring them back. Also my son was about 6.5lbs when we brought him home from hospital, he seemed a bit lost in the up to 65lbs marathon. But we managed. My daughter came home a little over 5lbs and really seemed lost in this car seat. We actually purchased an infant carrier style for her in order to fit her better. I don't think this car seat is a good fit for a 5lbs child.

Great Option!

We love our new carseats. Our daughter is comfortable in her "big girl" seat and prefers this to her "baby" seat. We feel great knowing she's comfortable and most importantly safe! Albee provided great, fast, reliable service. They were the most competitively priced, and we loved the free shipping too!

Love Albee baby. I accidentally ordered 2 Car seats and their customer service center was very helpful in removing one order. I've ordered from them before and would definitely again. Great prices and product.

We have no complaints. We already had one of these seats, and needed a second for our other car. Albee Baby had the best price.

Great car seat with high safety reviews. That is what sold me on this model. Britax has the best car seats for all around safety and price. This s the only brand our family has purchased for all 5 children. This was purchase #7 Britsx car seat.

Safe
March 25, 2013
We're on our third carseat, and once again we went back to this model. (Had to replace one of our two due to accident.) Super safe, cleans well, we've been able to keep little one rear facing past two in this seat.
Pros:
Safe, easily adjustable.
Cons:
Bulky and heavy.

worth the money!
March 21, 2013
I love this car seat! We purchased one about a year ago for my car (the main vehicle used) and a cheaper one of a well known brand for my husbands vehicle. We ended up getting this one for his vehicle as we hated the cheap one!! This one secures well to the vehicle and the straps dont get twisted, the two main problems of the cheap one. So glad we got this, wish we would've just spent the extra money in the first place! Fast shipping too :)

Love this car seat!
September 15, 2012
I am thrilled with my experience with Albee Baby, and the purchase of this car seat. We originally purchased a Recaro car seat. I felt I was well informed when I bought the Recaro, but since I wasn't able to see it in person before I bought it, I wasn't sure how it would fit in the car. I was very disappointed when it arrived. It did not fit well in my SUV at all, it was too high for me to see the mirror and my husband who is 6'3" could not fit in the seat in front of it. We decided to test fit the Britax at a local store, and I was amazed at how much better it fit. I does not take up any more room than the infant carrier, and I can see my son in the mirror perfectly! Albee Baby had the best price on the seat, and the Britax stroller we also purchased, and both arrived two days after placing my order. I am SO happy with my experience and purchases.
Pros:
Comfortable Small for a convertible High safety ratings
Cons:
Nothing!
