I really liked how easy it was to apply and to use the UV light. They felt pretty sturdy after I put them on, but with normal everyday wear, they actually came off in 3 days. I think making your nails really rough, especially near the cuticle would make a difference. I even cured each nail for 2 minutes to make sure the glue hardened. A bit disappointing since the package said it can last up to 4 weeks. I will try again with different nails.
