I'm testing a prototype Jon sent me. As luck would have it it hasn't been real warm since I received it so I can't tell if it will behave differently or not yet.
In all fairness to the original clip of Jon's, I tried to break it (since it was bent anyway) and couldn't*. So strength-wise it's good, just keep it out of the heat and you'll probably have no issues.
* I imagine if I tried hard enough it would break, but just using normal old man hand pressure it didn't even flex.
Nice warm day today (around 90) and I left the SDS100 in the vehicle for several hours. Came back and no issues with the prototype clip. Hopefully Jon can make it the same length as his original and in black (mine is white'ish).
