It works, it's just quite expensive and you don't get a lot of the masks.

It works, which is pretty amazing. The problem is for the price you don't get a lot of masks and the effect only lasts the night really.  So to keep this up you would need to do it twice a week or more...and at this price point the refills on this are just prohibitively expensive.  It might work just as well if you use a tightening cream with the strap...just not buy the refills (I might try that). But the refills on this should be brought down on price to make it viable to use regularly.
