I've been wearing Jamberry Nails for two years now. They are super easy, super fun, and last at least 12-14 days, if I don't switch them out sooner.
I haven't had any of the fungus issues people are talking about, nor have I experienced chipping with their lacquers. In fact, I just removed a lacquer/wrap combo from my hands with such ease, even after wearing it for 13 days. Even my 12-year-old and 8-year-old can successfully apply the Jams. Oh and their gel system is GREAT!
Bottom Line: Yes, I would recommend this to a friend
