Review on ALONEFIRE Rechargeable UV Flashlight With 365Nm Wavelength - Ideal For Pet Urine Detection, Resin Curing, Dry Stain Removal, And Scorpion Hunting: Includes Battery Charger And Batteries by Jesse Wells

Likes: Large lipo battery (32650 format) with separate charger, runs at least 30 minutes Great engineering on the heat sink, mine barely warms up after 10 minutes on Powerful beam, you can see dog stains in the carpet from across the room with all lights on. Yuk. Cures UV resin quite well on small projects (the beam is a spot a few inches in diameter).Dislikes: Have to pay attention to battery drain by brightness of the output. The cell has no Low Voltage cutoff and could be easily damaged from over-discharge. Not for OCD people. Don't bring this into your bathroom.
