I wish this seat have be test and revise before final production because it could be a great car seat . instead , the way that it fit into the seat as a rear face seat make it impossible to adjust the tightness of the strap , which equal a unsafe fit for you child . very disappointed . it may be different as a forward face seat , but that do not help we or own 6 month old . as insult to injury , the instruction be clearly -lrb- very poorly -rrb- translate from a foreign language , which make it impossible to understand . you basically just use common sense to get the seat latch because the direction make no sense . this be a huge hassle and I plan on return it immediately .
