do not pay much so i guess i can not expect much ... Main problem : - battery usage be terrible . my Apple trackpad which be use everyday last for week on a full charge of 2 aa battery eventho it be never turn OFF !! ... this keyboard , if leave ON will drain the battery in a few day ... regardless if it be use or not !! - rarely , but sometimes the keyboard key get stick ... not physically though so there be just repeat character tuuuuuuurn up on my screen ... - i wish it have a esc button versus otherwise : - Pairs properly between a MacBook & iPhone ... but i have to enter a new pairing key w \/ my MacBook almost every time ... this could be due to OSX Lion tho ... ?? Quality be not the greatest ... but it be a cheap price too ... lf the key do not stick & battery last longer for the same price . . i would be happy . if the manufacturer would like to send I a new one , i would be happy to see if it be any better & do another review ...
