Review (2/5): You get what you pay for...
As someone who uses professional products, I bought this to try as an alternative to acrylic. The polyresin is quick curing and less work than acrylic. Polishes nicely. My nails looked beautiful. Until 48 hours later when 2 nails broke. Nothing crazy within the two days other than getting dressed, watching TV, making a phone call on my phone and cooking one meal. No significant water exposure or any significant stress to the hands. However, as someone who maintains their professional manicure with professional products and even non-professional products - glue on nails are stronger and last longer than these polyresin nails. VERY unhappy after spending an hour doing them.
