I figure if the rims survive a bashing from my 2 and 4 year old boys, they can survive anything 
Brilliant video guys what a laugh

I don't think any of us doubt the strength of the shells or the polycarb rims, but I still have my doubts about the polycarb rim's playability as a drum surface. It still feels a little too loose and plasticky to hit. Sure the materials are strong but anyone who has played a roland or yammy kit will know what I mean. For example Roland rims are just a normal drum hoop except they have a thick rubber o-ring around them, which took me 5 years to break through the rubber on one pad (the snare of course

) Its a nice solid surface, yet still has a little rebound in it. The rim also sits up a little higher which is nice. I think part of this 'solid feel' comes from the fact that the rim is fixed to the shell of the drum in the standard way, with tension screws, and also re-inforced by thick rubber. This makes strikes feel more solid imo. 2Box rims may be strong but they feel a little disconnected from the shell. Sorry not knocking my kit I love it to pieces, just think the rims need re-thought...
