These glue on nails are a good option if you can't afford to get your nails done every 4 weeks. However, I have quite a few problems with them. For one, I am pretty sure I am allergic to the nail glue! After using it, the beds of my nails become extremely itchy and irritated. Also, the nails pop off very easily even if you use a lot of glue. This causes them to almost cost more money than just getting your nails done at a salon. Overall, they look very pretty while they last, but they might end up costing more than salon nails.
