I used to get them done which cost around £40 a month until I saw my friend's who had stick ons and they looked really nice. I used to wear them when I was skint but when I worked at a pub they used to ping off all the time. Anyway I decided to try them after one of my acrylics came off and took half of my nail with it, so bought some from Tesco by nailene, they were a pack of 200 for £8(!!!!!!!) and I have worn them for the past 2 months and haven't pinged any off. I change them every week because I paint my nails so I like a fresh set but I'm still on my first box of these nails, I honestly can't recommend them enough. Because they're not proper acrylics they're much flatter and look more natural, no one ever thinks I'm wearing fakes, and my nails underneath aren't damaged at all. They're a good length too they just need a bit of filing into shape, and you really have to paint them as they look crap bare, but honestly I love them - don't think I'll ever bother getting them done professionally again!
