Not too difficult, but takes practice.  Longer lasting than traditional polish
The polish strips are very thin and fragile, so it takes some practice to get them on without ruining them, but I was able to get a set of nice looking nails with one kit.  They lasted longer than traditional polish (5 to 6 days for me) but not as long as nail wraps (such as Jamberry) which usually last about 10 days on me.  I alternate the  Incoco with my nail wraps to give my nails some breathing time between wraps.
