BEST CARSEAT! We were in a bad accident! ·
Recommended Not Recommended

We bought this car seat once our baby grew out of her infant seat. We loved it's capability to turn to load her in easily. On a drive on a highway in-between LA & Vegas, we were hit from behind by a kid going 120mph. We slammed into the guard rail, and slid for over a football field. Once we stopped, I began screaming about my baby, and ripped the door open. My baby let out one cry, & SHE WAS PERFECTLY SAFE. The car seat is in perfect condition. This car seat kept my baby safe, in an accident that totaled our car. Just Buy It! It's worth the money. I've never been so relieved that she was in such. safe carseat. I am logging on today, to order the EXACT same car seat to keep my baby safe.

Unfortunately incompatible with my VW Atlas Caryl ·
Recommended Not Recommended

I was excited about this seat, but couldn’t get a stable install. I set up a video consult with Cybex (which I should have done sooner bc they were EXTREMELY helpful-they even got an engineer to try to help). Ultimately, it’s not compatible with my Atlas.

Wish we had it sooner! BB&B Customer ·

We bought this to replace our Clek Liing in my husband’s M2…yes, he fits a kid in the backseat of a coupe. He loves the 360 degree feature and wishes he would have purchased this initially.



Regret ma3martinez ·

Ugh I regret getting this car seat. So many problems and reasons why. It’s super jiggly and I emailed them and they keep saying it’s normal the dam clip keeps saying baby in car when there isn’t, when spot where you clip it in is a hassle and doesn’t want to close right ugh so much much more not Worth the price at all

Installing nightmare BB&B Customer ·
Recommended Not Recommended

I love this car seat but installing is an absolute nightmare. I’ve had it for a year and getting rid of it because installing it is too difficult. I’ve contacted the company, watched videos and they make it seem so simple but it’s the hardest car seat I’ve ever installed.


We love this car seat. BB&B Customer ·
Recommended Not Recommended

The only thing we haven’t liked about this seat is how heavy it is but it stays in the car and you don’t have to move it unless your child is driving with someone else.


The best there is! Brit ·

I didn’t realize how much of a blessing this would be when it was gifted to us. We absolutely love this car seat! It is comfortable-our baby boy actually enjoys being in it, it is safe-most important, and it is great for adventuring families like ours! The rotation feature makes it especially helpful when getting baby in and out of our keep wrangler. I would highly recommend to families on the go!

Life Saver! Kaitlyn MCS ·

This car seat is so revolutionary & a back saver! I have a history of lower back injuries due to my career as a professional dancer. This design allows for me to safely get my baby into his car seat while not putting myself in a bad angle that flares up my back! So grateful for this product & design!

Wanted to love it Jennifer Lewis ·
Recommended Not Recommended

I wanted to love it. It is very high quality materials, very easy to buckle him in. The swivel feature is great. It’s a hard install and very heavy, the car seat is not stable, load leg is terrible doesn’t add any extra support. I checked to make sure my car was compatible prior to purchasing. I can’t return it.

Not safe, serious design flaw suzanna ·
Recommended Not Recommended

The harness clip is dangerous. It has come undone several times on my almost 2 year old. I always check to hear the click and then pull it to make sure it is locked. It has come undone with her just arching her back, it has come undone after she has given her soft stuffed owl a hug, it has come undone with her putting her hand on the clip, over the button, but not actively attempting to push the button. This is a $550 carseat supposedly designed for safety of babies and toddlers. Even if my toddler was actively attempting to push the button, it should not release so easily. As a test, I locked the clip, ensured it was secure, placed my hand behind it to create some tension and ran my finger lightly over it. Popped right open. Refuse to let her ride in this seat anymore. Would not trust it to stay locked in an accident. I truly believe it may only be a matter of time before this item is recalled because a child is injured or killed. I sure hope I am wrong though.
