Hey man there are 2 things you can do. email the support and ship is back like i had to do with my old one and get a new one. i just got mine back after 5 months and the darn thing seemed to go through batteries like nothing and berely burn. that was untill i got new batteries and poped a disk made of tin foil inbetween the battery and the end cap. this bypassed the funky pin lock which is where all their power problems come from. now my laser burns through a 1.5 mm thich cd jewl case with ease. it will slice black tape in under 1.5 sec. i sliced electrical tape in half in 1 sec. it also poped a red,green,orange,and blue baloon without any black sharpie on it. give the tinfoil a try before you give up on the thing. i am currently going to be working on a metal insert or somthing to make it non micky moused. the problem is that the pin lock is too loose in most all of the E3 lasers and it will have its moments where it will look like a 200mw then look like a 0.1 mw. mine did this till i bypassed the retarded endcap with foil. now its always 100% power. btw make the disk wide so it touches the metal on the inside of the host and also touches the battery. you might have to experiment a bit. is this doesnt work then try a dif brand of batteries or just send it back for a new one. if you need help pm me or somthing. please let me know your outcome.
p.s. sorry for commenting on a month and a half old post
