Summary: Except for the beam dead-spot issue, I love this keyboard and would purchase again in a heartbeat. Even as such, it's lasted 4 years and still going strong, so I do not regret the purchase.
Pros: Great ergonomic design, nice weight and solid feel to it overall. Touchpad position and functionality is beautifully done-very responsive and accurate. KB has really nice tactile and quality feel to it, and editing keys are well laid out. Battery lasts many weeks with my HTPC/couch-surfing use.
Cons: Sometimes, even with charged batteries, the wireless "beam" looses connection to the USB receiver. Adjusting KB angle on my lap by a fraction of a degree restores the connection. This increases from a minor annoyance at times to downright frustration. Seems to be battery charge related, MOST of the time **but not always**. Sometimes on a perfectly fresh charge it will do this. I consider it bad enough that when the Adesso breaks I will not purchase another one.
Summary: this keyboard is pretty nice as others have said but it has one big flaw where as your typing the cursor will jump to other places since your thumbs will graze the touch pad making typing a harrowing experience. for months I endured this torture and even looked for a replacement until I found an awesome little program called TOUCHFREEZE. problem solved!
Pros: see other reviews
Cons: cursor jump while typing, location of certain keys, read below for solution!
Summary: -This seems to be the best wireless keyboard with touchpad product on the market, but it's not too good. You will typo like a crazy person if you use this to do any extensive typing. -Not sure about range. I use this so I can sit a few feet further back from my desktop so I'm not far away at all (3 or 4 feet?). It has never disconnected from thiis distance. -So far, battery life is good.
Pros: -Wireless doesn't disconnect -Touchpad works fine -Convenient as a wireless lap keyboard with mouse -Keys feel OK
Cons: -Duplicates keystrokes!!! Lot's of typo's -Everytime it wakes up (well almost everytime), it turns on num lock -- stupid! -Wireless dongle looks like its from the 80's (HUGE) -Not in the least bit ergonomic
Summary: My wife wanted a smooth mouse for her fingers to roll on. After receiving it we were very disappointed with the product. It is all plastic and very light weight (which is great if that is what you're looking for - we actually wanted a metal mouse area) The range, with brand new AA batteries was good if the USB key was in the front of the computer otherwise it barley worked. I'm thankful that this company took it back without any questions asked.
