Really good product
I have to say it is really helpful to improve skin condition.<br />After using it for the first time, I immediately can tell the difference.<br />I already recommended my best friend to try it.<br /><br />However, when you use it, make sure you use it on both side of face equally.<br />I have a small face. If I use it one side longer than the other, I can see the side using longer time become smaller. Thus I have to pay attentions to the time I use for each side. If it has a timer, it could be even better.<br /><br />Compared to the newest model, I think this one is more cost efficient. But I would like to try the newest  model next time since it really works, even a little more expensive.
