I REALLY wanted to like this laser. On paper, it has all the feature I'm looking for at a great price. There's one problem: THERE IS NO SUPPORT!!!! The user's manual is less than worthless. It only has superficial information like "put water in, turn it on". Any technical support questions take at least 4-5 days to reply. When you ask the Chat support ANYTHING, they simply send you the SAME WORTHLESS manual in PDF format!
I should have save my money and bought a more established brand that provides basic support in under a week. In English!
