Last time I had this on in a different colour it lasted really well, no chips at all, but in the end I was a bit naughty and peeled/picked it off when it started to grow out quite a lot/I got bored - I wouldn't recommend this and would say to get it removed properly. This time I soaked it off properly with acetone using the tinfoil method and it worked a treat. It looked fine apart from a bit of regrowth at the cuticle, still chip free and glossy before I removed it. My nails were really long after using this as obviously it protects them more than polish does, and were also undamaged.
I am thinking more and more about investing in a Shellac kit and doing this stuff myself though, it costs around £20 a time to have this done and I could really do it myself as apart from it being sealed under UV light it's not that different to polishing nails, which I feel I'm quite good at - as I've mentioned before, I'm a qualified beauty therapist so I could actually get all the stuff I need direct from the supplier/distributor with my manicure qualifications. Something to think about I think!
