The product arrived broken it difnt work at all at first but I repaired it. Sill I bought 16 line laser (only 12 lines works), also lines are not aligned. After few days if conversation with seller he suggested that I try to fix it .... REALLY? I decided to return the product but even thou I bought product with delivery FROM POLAND only possible option was to return it to China. Cost of returning it to China would be too high. I am resigning AliExpress for sure and this product is a toy, not for practucal use. Everything I bought on aliexpress was low quality anyway.
good tank to all
