Love Sally Hansen Salon Effects and they will last me for 3 weeks and then I only need to take them off because my nail has grown out too much. Easy to remove with nail polish remover. I constantly get compliments about my nails wherever I go. No one can believe I do them myself. They look every professional. My only suggestion would be to take your time when you are applying them. This is what I do to make them last for so long: Swab your nails with nail polish remover (even if you don't have any polish on), push cuticles back, shape nails, smooth out any ridges, etc (only use #1 & 2 if using a manicure board), open package and lay out your sizes first before getting started, wash your hands, swab your nails again with remover then apply as directed. I will usually put one thin coat of INM topcoat on my nails afterwards then reapply coats every 3-4 days or so (sometimes longer). The cool thing is you can slightly change the look by using a glittler clear polish (I use INM Northern Lights) during the second or third week. It really refreshes and gives your nails a really cool effect. There is no downside and worth every penny. Highly recommend!
