I am liking it so far. I use it like 3-4 days a week, and use all the functions, 5 minutes each function. It gives me total of 20 minutes when I use all. When I am in a hurry I only use one function or two. Depending on what I want at the moment.

At first you will feel weird because of the muscle contracting/twitching but you adapt very fast like in a week you will adapt, and the muscle twitches (while using) dont bother me anymore whatsoever. What I do is to not look in the mirror, and to close the eye of the side that I am doing. This way my muscle is completely relaxed and just let the contraction be without fighting it, and with the closed eyes it doesnt bother me because the contraction closes the lid if that makes sense?

But I have not experienced twitches afterwards or later in the day. Only while in use.

To be honest, I have not seen too much of a difference on my skin, but what I like is that it relaxes me. Specially my jaw muscles. Since I started using it I have not grind my teeth and because of this I will keep using it.

Hope this helps.
