SIIG JK-WR0412-S1 Black 81 Normal Keys 14 Function Keys USB RF Wireless Mini Multimedia Keyboard

Large enough keys, trackball, 3'rd mouse button

Certain multimedia keys press multiple times thus makes this keyboard unusable for HTPC

works great good range trackball is nice

needs num. lock light and the two button is hard to use and is stiff

Small and comfortable, but has big keyboard feel

Track ball is terrible. Feels cheap- and I experience same annoying double-click issues plaguing everyone else on here

Extremely convenient for HTPC usage. Good size, nice and portable but still has a big enough keyboard to not be uncomfortably awkward

Usually misses every other click. I have the receiver in direct line of sight and less than 6 feet away so it's most likely a hardware issue with the mouse switch, especially considering that typing is near 100

Mouse click misses maybe 1 out of 20 times, but not a big deal

Small, light, wireless RF instead of infrared like my old one. Trackball was responsive and easy to use. Like the "left click" button on the right side for one handed mouse operation

Keys are bit small to type on for someone with large hands. Arrow keys shifted over one key as compared to my old keyboard, so I'm finding my fingers on the wrong keys, hopefully I can get used to the new placement

Uses 2x AA batteries that last quite a while, compared to an old X-Gene I have that uses 4x AA and goes through them quickly

The trackball is rather small and has a tendency to stick if your thumb is at the 'wrong' angle - biggest complaint. Getting used to the smaller key layout takes time. The keys are much smaller and closer together than a standard keyboard or even the...
