Review: Esa facilísimo de instalar con la función clicktight, es un poco más costoso que otros muy populares, pero yo lo compré en descuento y vale totalmente la pena, además es muy acolchonado para comodidad de los babies, lo recomiendo ampliamente.
Review: My car seat hater enjoys the car much more in this than his infant seat. My 3 year old has one too and we love how comfortable they are, the less strict accident policy (had to replace a Graco extend 2 fit twice in 6 months bc of their replace in any and all accidents policy), that you can machine wash the cover with light detergent and how easy they are to install. Very high quality car seat that's very easy to adjust! CARSEATS WILL NOT PROTECT YOUR CHILD IF USED INCORRECTLY: -Top of chest clip should be level with armpits -Straps should come from below the shoulders rear facing and above the shoulders for forward facing -Slack should be removed from the hips, then tighten just enough so you're unable to pinch the straps at the shoulder vertically -DO NOT add any inserts, strap covers or head positioners that didn't come with your seat, they are not crash tested for your seat and will void the warranty in the case of an accident -Nothing should be attached to the seat or its straps (like binky clips, toys etc) -Wash per your manual -Rear face until absolute minimum of 2, it's their bone development that matters most -If you go see someone to help you install your seat make sure they are CPST (Child Passenger Safety Technician) -READ YOUR MANUAL) The group Car seat Safety on Facebook is extremely helpful

Sin duda la mejor silla del mercado, fácil de instalar y bastante segura. Mucha gente se deja engañar porque no tiene anclaje isofix pero la realidad es que el anclaje más seguro es usando el cinturón de seguridad.
