This digital scale from ProScale will blow your mind and completely fool anyone who sees it on your desk! It looks like a normal optical mouse, and really works! Plug in the standard USB cable and use the scroll wheel and left and right click buttons like you would with any mouse. Lift up the lid to reveal a high-accuracy digital scale with a blue-backlight LCD display, 100 gram capacity and 0.01gr accuracy. You can weigh your items in grams (g), ounces (oz), grains (gn) or carats (ct). The scale also features a tare function and auto shut-off after 60 seconds without use. The scale is powered by a rechargeable battery which recharges when connected to your computer via the USB plug.
When the scale is removed from the mouse, the empty spot can be used as a hidden safe for your cash, stash or jewelry! Who would even think to look inside your mouse?!
