Our kids used the CR for their SLI rocket. We own 4 of them because they were using two at a time for their rocket and we needed a backup set. Anyway, we always try to note where the split section of the small split ring ends up in relation to the rubber band. It's a nicely made ring, but I don't want the part of the split ring than can open be near the rubber band. That part of the ring can very slightly press into the rubber band. It's better to rotate that ring so that the rubber band is only over the double section of 'wire' that the ring is made of.
Talcum powder also works well for getting the rubber band into the CR. We replace the rubber band often. They're super cheap and we ended up buying a nice box from Uline that has hundreds of rubber bands. Easier to replace the rubber band often rather than waiting for a failure.
The only time the CR didn't work for us is when we forgot to turn it on!
