I have used this keyboard for a number of years now. I am a transcriptionist by trade, constantly typing anywhere from nine to 12 solid hours around six days a week. I'm very hard on keyboards and MUST have an ergo board because of my business. This is simply the best ergonomic keyboard I've ever tried.
Usually I ditch the mouse that comes along with it, but this time I gave it a try. I bought a replacement cordless Logitech mouse to go with the new keyboard, but I am shocked to find that I like the mouse that I got with this keyboard so much this time around that I have yet to even open the package on the new mouse I bought. I'll hang on to it because it's always great to have a spare, but I'm glad to know that the bundled mouse is now worth using.
You can't go wrong with this keyboard. Even when it's beaten to inoperability by constant, heavy usage, it's still a nice board to type on. I recommend it to all my colleagues. If you type for a living, dropping $80 on this board, even twice a year, is well worth the money to spare yourself the pain in your wrists!
