It is an excellent alternative to other brands on the market that are very expensive, and if you can't spend that money, this mascara works well and gives good results. I've been using it for several days now and I'm happy with the purchase.
I've got it on and after charging it it is working. Its my second day using. I have it on setting 3 for 20 mins. I'll leave an additional review if i see a difference in my skin after a few weeeks.
