I invested in one of these UV lights for Gel mani's and let me just say...Gel nail polish is the SHIZZZ-NIT!! Im a bartender, so nails were in awful shape (from all the water, sticky booze & chemicals in cleaning stuff) before i started using the gel polish. Now my nails don't peel, split, flake or crack AT ALL! They grow without chipping until i remove the gel polish, and when done properly, a gel mani can last 3 weeks or longer! Plus, it sure beats paying $30-$40 a pop to have your nails painted with gel polish in a salon! Buyer will be very happy with this item. :)
