I have had it for over a year and I love it! It was worth every penny. It took a little practice, but by my 3rd mani I had a salon-perfect gel manicure.
It helps if you have had a salon gel manicure first, so you have watched a pro do it. You must follow all the instructions carefully.
I just invested in the Gelish 18G LED lamp, as I'm in the middle of getting certified as a nail pro, so need to be able to do full hands, and not just 4 fingers and then thumbs. I use my original kit with Red Carpet polishes & Gelish polishes. You need patience, a steady hand, and orange sticks on hand to make sure there is no residue before curing. For me it was well worth the investment.
