Hey guys im sorta new to the whole Laser stuff but I got A question and would be very greatful if somone can help me out. I Got A Green 50Mw New Wish Laser But It Seems its cheap everytime i shake it it will turn off and at times it wont even turn on at all and ill have to shake and play around with the batterys any idea why it dose that ? Im thinking its the battery casing because it dose rattle a bit when i shake it

The contacts are poor on this model. try to clean the spring, also try to add some aluminium foild inside the barrel.
