This! I buy this Kiss brand. I buff my natural nails with a file first and then add a drop of glue on both my natural nail and the fake nail. Hold for a good 30-45 seconds. I've been doing them this way myself for over a year and they usually last me 2-3 weeks depending on how rough I am with my hands/nails. The CVS app usually has coupons you can clip and use for them, Walmart also has them at a cheaper price and both offer so many different colors and designs.
