Masks and Leaks

I read several threads from 2010, 2011, and 2012 on ideas for helping with mask leaks, including this:

At that time it appears the results were mixed on this product, more saying it didn't work for them than did. It appears they are now making these to fit a larger variety of masks than during the time the threads I read were posted.

Has anyone had good success with this?

Thanks!

I ordered one a few months ago, but it was so heavy that I didn't want to put it on my face; offered it here on the forum for the cost of postage. I sent it to someone, later asked him if he had success with it, he seemed to like it. That's all I know about it.
