Looking through this thread, I see some people had great results with the Insta-Gel Strips, but I didn't like my experience so much...
I barely got a week's worth of wear out of them, and the strips themselves seemed just like regular polish strips, with only the included small size of top coat to make them into "Gel Strips". When I applied them and whenever I got a chip, I got a strong smell of this nasty nail polish odor that lingered for about two days--not like gel at all.
At least the design was chip-friendly and more complex than I could ever do myself. My first hand was kind of wobbly looking, but the second looks better...although neither application helped with my wear time. And unfortunately, when I tried to stretch out the strips like you normally would to apply the flat sheets to your nail, I noticed the pattern cracking along lines.
(I paired this with OPI Gelcolor "Suzi and the Seven Dusseldorfs", by the way)
