Accident safe! Karmen D ·
Recommended Not Recommended

I bought this carseat because of the features and the ratings. Little did I know I would be coming back to rave about the safety of this carseat. My daughter and I were hit by a drunk driver when our car was flipped and totalled. My daughter was completely unharmed because of this carseat. I have to buy a new carseat of course, and I am buying the same exact one. Thank you so much Graco for making an incredible carseat!

Nice seat pain to install momof3insc ·
Recommended Not Recommended

I bought the Waze/tranzitions in November because I needed a more narrow seat for my new vehicle. Pros; comfortable, super easy to adjust harness, extremely lightweight, more narrow than other seats, easy to clean. Con: it is impossible to install. I've tried both latch and seat belt. It is impossible to get a tight install with less than an inch of movement without wrestling with the seat for a while. Overall it's a great seat and I would recommend it as long as you go into it knowing about the difficulty getting a good install.

It rattles in the backseat when no kids are back there. Easy install, fits fine, but rattling is aggravating. I got my nanny kid a better seat (got the extend to fit instead. No regrets)

Does not tighten all the way! Emily1016 ·
Recommended Not Recommended

I bought this and no matter how much I try or other people that are a lot stronger than I am, we can’t get this thing tightened up completely. It’s not a good car seat and I don’t recommend. It is comfy for my daughter, it just isn’t safe.

So disappointed Patri ·
Recommended Not Recommended

Bought this carseat about two weeks ago and i was really excited about it but the latches don't seem to tighten using all the anchors and seatbelt. All the videos ive watched having multiple people help on trying to tighten the seat not to move so loosely. Im so disappointed and will have to return.

Amazing seat! T Osborne ·

Got this seat to replace my 4 year olds accide after a car accident. And he loves feeling like a big boy, and momma loves the security of a 5 pt harness!

Ease of Use

Almost perfect! Janet ·
Recommended Not Recommended

The bottom latch by child’s legs is very hard to unlatch. It takes me 2 hands and lots of pressure. Also, the cup holder could be wider…..does not fit the kids stainless steel water bottles.

Happy Lmfart ·

It sits low, and the cup holders swing in. The crotch button part seems bulky between my kids legs and a little cumbersome but overall happy with this one!

Cant get seat to tighten down UpNorhtJodi ·
Recommended Not Recommended

I love the fact that its light weight but I can not for the life of me get it to tighten down so there is less than the 1" give. I even had my dad help to put more pressure on the car seat and no matter what we did or tried we cant seem to get it.

Only thing i dont care for Mommy85 ·
Recommended Not Recommended

I have used graco products for both my kiddos. I love how far car seats have come with more convenient features. I have been happy with everything graco i have bought with a small exception of this one and the cup holders not staying in and now we dont have any. I dont understand this feature since my child has been the one to pull them out herself.
