Review (2/5): Electrical problems right away.
I purchased two of these. One had electrical problem on the first day. I was able to return but they deducted $6.00 for returning it. $6.00? It sucks because it was manufacture problem in the first place.
Update...
I actually own 4 of these. I can confidently report the following to help my fellow consumers:
1. The front sliding (up and down) door is not practical... it's more like an obstacle. Customers fingers keep hitting this door and smear the gel.
2. The supplied power cord (charger) went bad in 1 year.
3. On the back (slightly to the right) is a hole where you can plug in the power. Well this opening (or this thing) is not very well made therefore instead of holding the electrical prong (the end of the charger) it would come loose and render the machine unusable.
I need to order six uv lamps and will definitely will not purchase these again.
