Review (3/5): Works great, but needs additional shielding
The unit works great, dries the gel quickly with no issues. The problem is, the UV reaches at least 18-24 inches from the unit, so any gel you may have near the unit will also get cured/hardened. I built a cardboard shield to place around the unit when I am using it, which works, but really the unit should be built so that it does not allow the UV to escape so far.
