Summary: I have grown so used to this keyboard that I can't live without it now. After 3 years of heavy use the keys are beginning to stick and I need to replace it. I just love the integration of the trackball and mouse type buttons into this keyboard, it is so simple to use.
Pros: Right size, long battery life, great trackball much better then a separate mouse. Good range.
Cons: Does not last forever, trackball needs to be cleaned on occasion requiring the removal of the keyboard cover.
Summary: This really is a solid contender for a must have for any HTPC. I keep it on and in my drawer for whenever I need it. All you have to do to wake it up is hit a keyboard key (trackball/mouse click don't count).
Pros: Great range. Battery Life is great with auto turn off (keyboard wake). Does everything as advertised.
Cons: Trackball gets worse with time. You have to press it down to make sure it "tracks" more and more. Not 100% in that department but it is still managable
Summary: Definitely go with Adessso besides the feel of the keys and a slight price jump the Adesso beats the Iogear in every category.
Pros: -The keys feel very solid -Lightweight -Mouse wheel very effective
Cons: -Range/ line of sight. Obstructions do make a difference and the range is not as good as the Adesso. -Shift and Enter placement are off. The natural placement has been skewed to make room for other keys causing mis keys. -Batter life while decent is less than the Adesso. -Left and right mouse key...
Summary: It's a little compact and doesn't have a number pad but great for the net. I didn't try it for reception out in the main room where it would most likely work fine. Nice little unit.
Pros: I have the PC in the closet and use flat screen TV as monitor. At first it would hang and not work properly. I figured it was a signal problem so I added a 4' USB extension to get the receiver out from behind obstructions and it works like a charm now. It's handy having the mouse and keyboard fun...
