I used the Microsoft ergonomic keyboard from the 1990's as a medical transcriptionist with no hand or carpal tunnel problems. I had started with wrist problems and the doctor told me to get an ergonomic keyboard. I only knew about Microsoft and that is what I got and used up until this year. I got a Logitech because someone told me they were better. They definitely are not. I don't like the shape, I didn't like the key placement. I tried and tried. When it kept losing the wireless connection I finally gave up and ordered the Microsoft board and mouse. The Logitech keyboard and mouse also started my wrist problems again. I am so happy I went back to Microsoft. They know how to make ergonomic keyboards the best of anyone. I used Microsoft ergonomic for almost 25 years and no wrist or hand problems. I am very happy after having the Microsoft ergonomic once again. I have been using it for about a week and the keyboard is finally feeling natural to me again for the key placement.

Microsoft Supplier Problem I've ordered this Business Model 5 times from different suppliers. In every case, the keyboard has arrived in its product box replete with factory-applied identification that corresponds with the (more expensive) "Business" model, but contains the lesser Home or "Retail" model. (The "Business" model features tougher key surfaces and more functions, but looks at first glance nearly identical to the "Retail" model.) It's obviously an error at the Chinese factory for which WalMart bears no responsibility, but I would discourage any prospective purchaser to ascertain whether or not the model offered is indeed what's to be shipped - that requires physical examination before shipment, not just reading the box labeling. I've used this type for many years, and have been highly satisfied, having at this point worn the identification labels form many of the keys. Was looking forward to receiving a brand new replacement, but am frustrated at every turn by the mis-identification issue.
