Review on GKCI Touch Lamp: Portable Table Sensor Control Bedside Lamps with USB Charging Port - 5 Level Dimmable Warm White Light & 13 Color Changing RGB for Bedroom/Office/Hallways by Stephen Hobbs

The title speaks for itself. The control range of the wireless controller can be 10 feet under the best conditions; When doing this you need to point the controller very carefully at the very small hole in the base of the lamp as the tiny hole is directional. I would have liked more range and a larger, less directional sensor aperture. A good example of what I like is my TV remote - I can point it at the ceiling and the invisible infrared light bouncing off the ceiling is enough to control the TV anywhere in a 400 square foot room . legroom. One more thing, I hope I can open the base to replace the battery when it runs out of charge. I would hate to throw away a perfectly usable lamp just because the battery will eventually die. There may be screws under the anti-slip pad on the bottom, there may not be. If not, I'll always take a hacksaw and cut it open whether you like it or not.
