    Review by Damon
    The pump is noisy but system works great at delivering the necessary air supply. I have been using half mask respirators for years now and these are not the best masks. The mask flex's too easily and allows air to blow into your eyes. It gets the job done at an affordable price but I wish the masks were a little more heavy duty. Then you would have a great system.
