I have have this logitech diNovo Edge keyboard for 2 month now . I read the other review and this one be the only wireless keyboard that other reviewer be consistantly happy with . it be significately more expensive than other sell on Amazon . but my experience so far be that it work prefectly ! the lithum ion battery and bluetooth communication be worth it . I be glad that I spend the extra money and be not disapoint . the review system work great !
