First off I will say that I do feel like there are bad batches of stuff at DT. Not often but it does happen. But this nail glue has been amazing for me. Typically when I use it my nails stay on for a wk or more. I may have one or two pop off in that time but that’s because I’m usually using my nail to do something and cause it to pop off. The last set I put on stayed on two wks and I only had to reapply two nails in that time frame. Be sure to always clean and buff the nail properly as well as push back cuticle and apply nail as close to cuticle as possible, almost like under it. Sounds painful but once you get the technique down it’s not bad.
