I believe it's a top-tier UV flashlight. Its UV output is very strong, and its design seems quite good. The only downside is that it won't work with standard flat-ended 18650 batteries because the springs are only on one side of the battery compartment, but this is quickly fixable with a soldering iron. It's quite heavy (over 500g),but I don't mind that. In general, I would recommend it.

Es fuerte y como se anticipaba.
