Review on Hatori Super Small Mini LED Flashlight - Powerful Pocket Torch for Camping, Emergency, and Outdoor Activities - Battery-Powered Handheld Pen Light with High Lumens by Benjamin Robinson

It was a nice bright bright light but after putting the battery in I opened the front to see how well the reflector and case fit. When I screwed it back on, the light didn't come on. Then I noticed that part of the LED was lying on the table in a plastic case. The LED appears to be in two parts: one of the silicon chip arrays is still attached to the circuit board, and what fell off was a plastic-encased gold circuit that was on top of the silicon chip. Of course it was a defect that upon mere inspection of the flashlight, the glue separated the functions of the two chips! I will be returning this Revain product. I hope Revain doesn't take the blame for this defective light or the seller. This is a quality control issue and this LED should not have been fired for flashlight applications!
