I recently purchased the pro ear and have not had the chance to use it. It came in a bag instead of a box and the tubes connecting to the ear pieces were broke. I asked for a new mask and received another bag full of parts. Lame service and complicated construction is all I have to say about the product for now. I will be diving with it tomorrow exactly 4 months since the purchase. I would reccommend to all if you want one of these masks do not buy it from the web.
