I got this on sale so it was a fantastic price! It stayed on well and definitely defined my lashes (fuller, longer etc.), I accidentally slept with it and it stayed on nicely. The only issue I've had is the extension part fly everywhere even when I try to pull the wand gently.

This mascara with lengthening extensions is a very good product, one you manage to figure out the best way for you to use it.
I find it takes a little practice to get it right, but when you do, it's worth the effort.
This is NOT a product for anyone who wears contact lenses.
I find it best to do one eye at a time. It takes me about 5-8 minutes to fully apply the product to get my desired result.
Make sure you cover every little fiber or they will get in your eyes and make you crazy.
If you are patient, this is a fun mascara for very dramatic looks.
