My nails ended up coming out rough and uneven on the edges, and with polish on my skin. They also don't have a variety of colors to choose from - a lot of reds, a lot of blues, but not much else without getting into the "add-on" (+$15) category.
They had designs and special polishes you could choose from. No cuticle oil during my manicure. It was $50 for a gel mani and regular pedi.
Also, I thought it was strange that they removed the gel polish with a drill instead of just soaking it and scraping.
