I like it!

I noticed that the production model is quite a bit different than the prototype shown in the vid ...

The prototype was going to make the box too narrow, and the flat top surface ... that someone might try to land on ... might buckle under their weight, causing an ankle injury (but still saving a more severe ankle injury). I think the minimal dimensions of the "flaps" in the production model have improved this, but I question if there's enough material to truly buffer the impact. Even so, anything's better than hitting solid metal!
This collar actually reduces the inside dimensions of the pit, so to be used for official meets, it may need certification ... or was this supposed to be used only for practices?

I hope certification (if required) comes without much hassle from any naysayers. It's not as good as the Skydex box IMHO, but for retrofitting an existing box, it's the best ... and least expensive ... alternative that I've seen!
One concern I have is the density of the foam. Current rules specify "2 inches of foam around the box" (or something like that), yet don't specify the TYPE or DENSITY of the foam. It would be ridiculous to use a very soft foam ... yet that's within today's rules. A foam with the density of something like Skydex would be best. The foam needs to be dense enough to prevent hard impact with the metal (and runway) underneath it ... from a 200 lb athlete (or less) falling 21 feet (or less). I think the Skydex box meets this criteria, but does the SafetyMax Box Collar?
