Review Content perfect for travel or at home Great to use in my living room or in a hotel room . compact easy to use ! Decent light but stem is too short Stem is short so if your USB ports are at the bottom (closer to your hands) of your laptop its difficult to get good light on the keyboard without interferring with your sight. It does work ok if you put it in the included base rather than directly into the USB port. A Terriffic Invention! This is a great product. Not only does it illuminate those pesky top-left-corner keys, but it fits right in my USB drive too! It runs completely off my computers battery as well as the D battery that sits right above the tiny lightbulb that needs to be special ordered. Its sleek. Its easy to use and assemble, once you find those tiny screwdrivers to fit the microscopic screws. My old lamp just didnt do the trick. I could only see the rest of the keyboard. Luckily, other people must have had this problem, so someone FINALLY invented this! It perfectally brightens up these keys: "`/~, "esc," "1/!," "2/@," "f1," "f2," and even the "tab" key!!!(see? I can SEE the "!" key, so I use it all the time!) All in all, great product. Perfect for when I want to sit in the dark and type emails containing `~1!2@ and without my wife hearing me. Buy this for all! Super contemporary and sleek! I would not buy this again Could not see key board at all Review This product looks better than it is advertised. I wish I didnt buy it and strongly encourage people to buy a real humidifer, not the petty, cheap, waste of money one here. Invest in the real thing, way more worth it. This products is way below expectations.
