I was a bit nervous buying this after some of the Rubies reviews were not so great.  The mask is not perfect, but definitely very nice for the price.  It is secured in the back with velcro, but it's done very well with the velcro inside parallel to the seem for a good fit.

The quality of the fit depends upon your head size.  Another reviewer said that it does remember folds, but I found they easily came out as the mask is latex and stretches once it is on.  Everyone thought it looked great.
