great for a beginner like me [SEP] this one is easy to use and results are great i have it for a couple of months now that is when i decided to do my own nails with gel my sister in law recommended this machine because it was similar to the one that she has it is not used much because i do my nails every weeks original drills are good for some applications but i got a set of diamond drills for russian manicure since then i never had gel peeling off from the bottom which was a common problem when i did my nails at the salon because i clean my cuticles with this machine i remove old gel with this machine as well i am a very satisfied customer
