Laser Pointer Batteries
broken laser pointer?
Hi everyone, I have recently bought a new laser pointer (http://www.amazon.com/Dimple-Finish-Double-Flashlight-Optical/dp/B000I0YIX2/ref=pd_bbs_sr_2?ie=UTF8&s=electronics&qid=1228600387&sr=8-2) from Amazon and it broke within days. Well here’s the story… The first one broke and I had to get a replacement which was for free. But after I got the replacement, I fiddled around with it, and it broke also (and I wasn’t throwing it around or being careless or anything). What may have happened was the issue with the battery. You see, for the laser pointer, I think the battery needs to be place within a certain order of + and -. I had put it in as – and +, which may have broken it. This happened with the first one also (I only realized that this may have been the reason 2nd time around). Is there a laser expert here that understands if this is the problem, or is there something else which I may have done? Thanks a lot everyone!
can u give suggestions as to how to fix it?
I think the quality of the lase pointer is not very good.
