Great features but huge flaws and obsolete - PACT MKIV XP Timer and Chronograph

I bought one a while back and the features are amazing. When I bought it I think it was in a class of it's own. But through using it there were some huge issues that became obvious. The biggest problem is that it drains 9V batteries within a few hours. And when it does the microphone stops reliably picking up the shots. There's no adjustment for sensitivity so it isn't reliable for use at a match or for dry fire. That means it's only good for live fire practice. The tech support for Pact is also terrible and when you finally do get a hold of someone they will tell you to change the battery. For the price I would recommend an AMG labs range commander, smaller form factor better battery life and all features you need.
