I have recently started using Lily & Fox nail wraps, and overall I'm very happy with them. They're cheap as chips and have free postage, but come from the US, so take a good 3-4 weeks to arrive.
Without doubt, they don't look as glossy as salon gels and aren't as hard wearing, but at that price point I wouldn't expect them to.
I can get them to last between 5-7 days. I do apply a topcoat, but it's an old Barry M one, so I'm thinking I need to get something of higher quality.
Crucially, for me, they're super easy and quick to apply. Just stick on, add top coat and your done. No lights or complicated and expensive paraphernalia needed. And they're super easy and quick to remove with ordinary nail polish remover.
I've attached a photo of my current set, which are showing some wear as are 4 days in, but I've been cleaning, washing, dog walking, packing and unpacking for hols and swimming with them.
Here is what I've also tried and the reasons I didn't like them:
Sistaco - powders were messy. Took bloody ages to put on and an age to get off. I think the entire process would take me about 3 hours. Not worth it.
Holy Grail Nails with UV top coat - again, took bloody ages to get them off, even with the "magic remover" stuff they sell. And I've no idea what was in that "magic remover" but I got it on my cuticles once and it burned!
Isabelle Hammon at a local salon - I had these for about 12 months and stopped when, in my opinion, it became too expensive for what it was. When I had my last lot removed, my nails were destroyed. They were paper thin and had no strength at all, I was so upset. It took about 8 months for them to get back to their normal look and feel.
