  • Great brand
Color: High Street
I have bought this brand of car seat since my son was born 8 years ago and have trusted it with my 3 year old daughter and 1 year old twins. It’s definitely a good family brand.

  • Great carseat, but be careful when taking it apart
Color: Dunes Edge
Pretty good carseat. My only complaint is when you need to take it apart to clean the slots to put the straps back in is in a really difficult spot. It should come with some sort of tool to help pull it through

  • Do NOT buy this Cheap carseat!!!
Color: High Street
Absolutely hated this carseat. We bought it for our mom's house so she would always have a carseat when she has our kids and if we flew to visit her we would have a carseat and wouldn't have to fly with one. #1 highly aggravating to install and didn't like the way it fit in a truck backseat. No matter how we strapped it down, every turn we made it would tilt over with our son in it. #2 We've had multiple carseats and even rented some when traveling around and this was still the WORST one we've ever had! #3 The cup holder kept falling off so you can really tell the quality of how it's made. The whole seat has a cheap feel. #4 Our child is still Rear facing and it was extremely difficult to get him in and out. #5 When the carseat is Rear facing the tightening strap for the harness was unaccessible. As you can imagine that is very frustrating! I HIGHLY do NOT recommend!!!! ... show more

  • Great for the price
Color: High Street
Bought this for my 2year old. It was a little hard figuring out how to adjust the straps probably because I was in a rush but once that was figured out strapping it in the car was a breeze my son loved facing the front. I wear my nails long and I don’t find it too difficult to get him in and out of it. ... show more

  • Okay
Color: Dunes Edge
The top broke and we only had it about a year. It was easy to install and adjust, but the quality was on the lower side.
