I've had my nails done religiously for 14 years. I started at the salon with liquid gel (I'm talking full build with forms - they look like acrylic) after about 10 years I started doing them myself at home. I am super picky - for that 10 years only one person did my nails.
I was introduced to gellies while visiting a friend. I used hers once on a few fingers and I was hooked. And that says something big!
The only downfall I've found is that after about a week mine tend to lift in the backs and my hair gets underneath when I'm pulling it up in a pony or washing it. HOWEVER I have oily nail beds and the fact that they even last that long makes up for it.
