Hi there, I am a new member. I just recieved a Deal Extreme Laser, it was well worth the investment! I made some high quality goggles and got the rechargable e2 bateries. At first, the e2's overheated and may have caused some damage, but that's because the Deal Extreme spring for the batteries was bent and touching the side. I bent it back, and no problems for now! After the thing overheated however, it didn't shine straight until it cooled down, now things r fine, I can't wait till nighttime and then I can post some pics. I can see the <200mw beam in my room in the day, but not outside, These summer days r toooo long!!
