Cut up upper lip even on the sidelines
I did not having trouble fitting this mouthpiece with the boil-and-and bite technique listed, however I did have issues with the hard plastic piece's attachment in the front to the gel. The joint kept rubbing my lip even during insertion and fitting and I've still got a sore there 3 days later. Furthermore it was very difficult to breath and talk. I found it very bulky compared with others (i.e. Under Armour Mouth guard original for contact sports and others), I could bear the gagging and choking but it is more pronounced that with very similar mouth guards designed for impact sports. bottom line: I wasted a bunch of money on this poorly-fitting, expensive, and difficult to wear device, as for it's protection during play? I have no idea. But, I can tell you that it's so uncomfortable to wear that the chances of someone wearing it are lower and therefore even if it did preform it's job well it's almost pointless.If I were you I would pick a different product.
