I've had many issues with this glue. 9/10 times, when I tried sticking the nail tip on my client, the nail will stick for a short period of time and then it will come off when I'm either buffing and/or shaping the tip. The glue does not hold that well. It's also resulted in my clients nails breaking because the nail tip is not sticking properly at all so the free edge is breaking. The overall packaging and the application brush is great in my opinion, the formula on the other hand ain't. I have an unopened bottle of glue and I honestly want to return it and get my money back because the glue is personally not worth it. I also think that most the reviews that are saying it's "perfect" is a scam. I either am doing something wrong or the glue is just not overall good.
