I got it two days ago, installed it, quite hard to press the delrin down. Well, done it, put some noalox just in case, and today, again hot button. I have to say, I also see the spring as part of the problem. The button wobles a bit, thus making better or worse contact depending on how you press it. VA could have done a much better work with the button, they tried something different and it's a failure.
I love the PV, but I'll have to fix it myself somehow. I'll see if I can get some magnets to start with...
