Hello dear customers,

Recently we got some complaints saying that the laser unit did not work. Please kindly be advised that there is a protective dot (tin dot) on most of the laser units. It is for protection purpose to prevent static electricity damage to the unit. Please remove it carefully with a soldering tool(a heated iron is ok). If you already removed it, but the unit is still not working, please contact us for advices.

Please do not leave a negative feedback without contacting us first. Please kindly give us a chance to help to solve the problem. Many thanks for your understanding.

Best Seller
