I've gone through 4 of these over the years. The ergonomic "fit" is wonderful for someone like me who works on computer all day. However, the less than "excellent" is because I'm on my 4th one for little quality issues, like the last one got a broken lift-leg on the backside, causing it to rock and not be the right angle. Seemed very flimsily made and so top quality is just not there. I would have LOVED to report here that I've only bought one.
I discovered this keyboard several years ago and since I work as a medical transcriptionist, comfort and ergonomics mean everything when typing 10+ hours a day. I have exclusively used this keyboard since ordering my very first one. I even connect it to my laptop to use. When I got my first one, I had been experiencing horrible pain in my hands, wrists and arms. Within a day or two of using this ergonomic keyboard, all of the symptoms were gone and have never returned. It took about a day for me to get used to the ergonomic layout. I can't guarantee everyone will have the same experience as I have had, but my personal preference is and has been this Adesso ergonomic keyboard. Overstock offers them for a great price! The only reason I gave it 4 stars on performance is because I have had to replace mine a couple of times but that could be because I type so much on it! I will replace it when the keys get "sticky" (and I do use the canned "air" to clean it), but that is usually only after 12-18 months or more of lots and lots of use.
