Sure, no criticism of the product intended, people obviously really like it.
My personal comment would be to make a larger version that covers wrist and forearm, maybe articulated with two or more pieces of the rubber. I have experimented in the nets with wearing the medium sized one plus the large one and this covers me almost up the the elbow. Still comfortable and light weight. Mostly academic for me though as I'm very tall and have never been hit on the elbow (yet)
