I do not know if the keyboard I buy have be use before -lrb- the packaging look a little suspect -rrb- but when I use this product , it be always a guess game as to which key would not be work - sometimes one or two sometimes 10 or 12 . I really , really like the concept ; I think that it increase the usability of the Palm 100 % since you can keep it open on you desk and enter stuff very quickly . I hesitate to talk badly about anything Palm since I have have one for 5 year and do not go anywhere without it . Suffice to say that I be very disapointed .
