Another great Crear product! This is an excellent base gel whether you use it as an overlay over your own nails or as a timted base gel for nail extensions. The self leveling and strength is amazing!! This is perfect for pros or the DIY nail enthusiast. I applied this product to test the strength by wearing it as an overlay over my own nails to give them a break and let them grow out. The first lifting appeared after week 6 and the remaining fingers lifted over the next 8 days. I was able to get more than 6 weeks of wear. When I removed the final gel I was surprised to find my nails were not brittle, thin or weak as with other products I used in the past. I highly recommend it to anyone looking for a great multi function base gel.
