I buy my first m natural keyboard over 10 year ago to help with carpal issue . I can not imagine how many time I have press each key but my first keyboard finally fail after more than 10 year ... so I buy another one just like the first . as I recall , it take a few day to get use to not have to scrunch my elbow into my ample side to position my hand on the key . once I get use to hold my hand in a `` natural '' position it immediately become evident to I how much nicer this type of keyboard be compare to the `` standard '' inline keyboard . for the price it seem like a great buy to I . if you amortize the purchase cost over the life of the keyboard it be very inexpensive . I use my computer everyday and do not expect to ever use anything but a natural keyboard . it work for I and I would recommend it to everyone .
