WORKS
It  allows room between you and the mask to breath. I would have like a more prominent nose piece making the bracket a little longer and easier to place over mouth and nose at the same time.  The product is not bad for the price. It is well made as far as durability. Instructions on how to use it is lacking a lot. Had to actually go on YouTube to find out how to use it because there was no instructions on how to use it in package.  Works but needs more work on construction and including instructions.
