You can replace the O-ring yourself if you want. Just get some size #011 O-rings from amazon or hardware store. Please note that is the same size O-ring as the SPY knob uses. To get the Droid apart you use a sewing needle to push in the little hole in the lock lever. The lever will come off and you can then replace the O-rings. The thing you are pushing on is a short wristwatch band spring bar. Don’t let it fall out of its hole in the Droid while it is free from the lock lever. Don't let it get away from you, it is a spring.
