I used the OPI
I used the OPI one for the first time last week and I got three or 4 days out of it. Then I used it yesterday and got like 12 hours out of it. The first time I did my nails then went to bed, the second time I did my nails and did the dishes and laundry and the polish literally fell right off by the next morning. I did my nails again last night and used it, and I have a few small chips but no peeling yet.
The last 2 times, I did a rather sloppy, quick job, so that may account for some of it. I am still experimenting with it, but I do like how easy it comes off.
