Summary: Ordered this keyboard about 6 weeks ago for my wife to use at work to alleviate a nerve problem she is being treated for in her arms. She finally convinced her Fortune 300 company to install an under desk keyboard tray, but they left her with a USB keyboard and mouse. We purchased this wireless keyboard with mouse features to fit the tray .
Summary: I've used many previous wireless keyboards - all with significant faults - but the Adesso WKB-3000U gets it right. It features great ergonomics, scroll wheel, durable optical trackball, dependable radio connection with small USB transceiver, excellent battery life, handy on-off switch, forward and back keys - and much more for a very reasonable price. For decades, I have used wireless keyboards daily, and the Adesso WKB-3000U is the best I have found.
Summary: worked marginally well for a while. although, the debounce of keys appears to be a little flakey. eevery once in a while appears to get "tired". at that point stops functioning well until restart. other wireless keyboard doesnt display same issues so i'm left to suspect this device. at range appears to really start to issue multiple key strikes. range is shorter than advertised. two keys stopped working middle of typing have not come back since.
Excerpt: I had a siig keyboard and it had no range. The adesso keyboard works like it should. The USB is in back of the media PC and has great range. Nice ergonomic feel. Worth the money. Got it super fast from B & H and at a great price.
Summary: I have in front of me 2 Adesso keyboards. The WKB-3000UB (obsolete) and the current WKB-3000U. The old one, the -3000UB, had its faults, but its ergonomics were by & large excellent. It had a full-size backspace key, a CTRL key on BOTH sides of the keyboard, and the DEL key on the top right - not in the very corner where it belonged, mind you, but close. The scroll wheel and L-R mouse buttons were darn near perfect.
Summary: Shopped lots of Wireless keyboards. I give this one a 4.5 rating. PROS: Chose this for price and features. Had it for a month, Worked right out of the box with no setup. I love the Trackball, it performs flawlessly. Lightweight but It's durable, I already dropped it off the couch onto a hardwood floor, put the batteries back in and no issues. Turns itself off after 30 minutes if you forget. CONS: Keys are a little smaller than I'd prefer. I have big hands.
