Must get
Great car seat, comfortable and safe. Perfect for new and vetern parents. Never have to worry about being to tired and forgetting your child in the car because your phone will send you an alert if your to far from the car, it will send you an alert if your toddler unbuckles while driving, and heaven forbids you get into an accident but it will send messages to your emergancy contact's (it will send messages to if you leave your child in the car and not respond in time. All car seats should have this feature. Fabric is easy to remove to clean. Cons- This has to be one of the heaviest car seat out there (over 30lbs) makes traveling or switching cars a little frustrating. Doesn't have a built in cup holders. Again moving seats or traveling makes it easy to lose or misplaced. But also, sometimes it moves on the seat and the cup tilts.

Amazing quality, extremely secure!
I've been using car seats since my oldest was born, 16 years ago! Safety, comfort, and features have changed SO much in that time. I am usually a loyal Graco and Britax car seat purchaser, but this seat won me over with the extra features. The fabric is smooth, soft, and nicely padded. The 3 way adjustable headrest is going to come in so handy when my LO gets older. Installation was fast, we're talking less than 2 minutes rear-facing. Having multiple recline options means not having to use pool noodles to get a proper level. My LO is 10 months and was all smiles for her first 30min car ride in this seat. I would highly recommend it if you are looking for top of the line safety and comfort!

Don’t miss out on this deal!
I wish I would’ve caught this sale. I purchased the blue seat for my 18 month old. I absolutely love this seat. My baby girl is super comfortable in it! Quality and design are on point. It’s not too bulky but still secure. I prefer it over the Nuna seat.

Huge yes for us!
My really long 10-month-old used to hate being in a car seat. I loved the reviews and safety ratings on this seat so I decided to cough up and pay the hefty price tag. It has been a few months, and I can not rave enough about this buy. The car seat is easy to clean and get him in and out of. One of my favorite features has to be the side magnets to hold the seat belt out of the way while putting him in! My son no longer hates car rides and often falls asleep comfortably.

SUPER COMPRA
ESTAMOS FELICES CON ELLAS, MIS DOS BEBES VAN SUPER COMODOS. ESTAN MUY BONITAS EN DISEÑO, LA TELA ES RICA Y ES FACIL AMARRAR Y DESAMARRARLOS DE ELLAS. EL APP FUNCIONA SUPER BIEN POR SI SE TE QUEDA UNO DE LOS NIÑOS EN EL COCHE O UNO SE LLEGA A DESABROCHAR.

Problemas en cinturones
Los cinturones se atoran constantemente y no corren. Tuve que desarmarla por completo para solucionarlo, pero el problema continuó.

Excelente Silla
Muy completa el asiento de carro, si es algo brumoso para un carro sedan "común" pero se ve sólido y cómodo, si funciona al 100 el sensor en MX, solo que no es muy buena la App.
