I recently bought Sanwu's 1.6W Laser and it is almost worthless. I can't see the beam in foggy or dark areas. I can't even see any light from the laser unless I am an inch away from the surface I'm pointing it at. I've heard good things about Sanwu on this forum and I expected better. 2 Flat Top 18350 Batteries do not work with this laser even though that's what Sanwu's website said to use. I am using a 18650 Button Top battery since it's the only one that will work. This is advertised as a True Burning Laser with power I wouldn't expect. I certainly didn't expect what I received after I read and purchased the laser I thought I was buying. I've typed the URL of two videos of the laser I received.
