After wearing my inPulse for five minutes the wrist strap popped off and now I can't get it on again. The spring bar goes in just fine by it self, but together with the strap it refuses to snap into place. Is there a special technique or modification that eases the installation?

Also it would be nice with a way to prevent this from happening again. It wasn't even on tight so it shouldn't have come off like that.

I had this exact issue with mine. What I ended up doing was shaving off a bit of extra plastic on the band to allow it to fit a little better. It has only popped off once since, but was easy to put back on.

I popped mine off to test force required, and found out, if you grab a small screw driver like one for glasses, and push down and in on the pin, pretty hard, it will seat back in the hole. Took me about 5 minutes to push just right, but was finally able to do it. I'd make a video of it, but I don't want to have to try putting it back in again.
