The Virtue clock.
As long as it's got fresh batteries in it, it's accurate and definitely has a few nice features. All it takes is tapping the trigger and you're good to go, and then you can program timers, a velocity limit, ROF limit, and even name it.
Although, it's VERY expensive.
You may call it fat, I call it bounce padding.
If I say "the safety frame claim is bull****" I'm not ripping on PE, the SL8R is my favorite gun EVER. If I say "DMs are overpriced" it doesn't mean Dye is a bad company, I want an NT11 in the worst way.
However, when I say "The Vapor is overpriced and not very good" I mean it. I won't have one unless it's cheaper than what I can get a G5 or Proton for or free.
