Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
I've tried this UV-light to look for scorpions in France. It works great. The output is enough to easily scan a wall. The scorpions light up brightly. It seems to be quite sturdy and well made. Although that is just feel and looks, haven't opened the switch or anything.
Cons:
The contact between the drop-in and the host is not great. Best to wrap the module in aluminum foil or something to improve this.
Other:
It is not 3 watt. I measured 1.3 watt with a fresh 18650. But you do not want a 3 watt anyway (battery life and heat)
Bottomline:
If you want a flashlight to look for scorpions on holiday (or at home), this one will do fine.
