I just bought and hardwired a new V1 - based on how many folks on this and other forums swear by them. The install was fairly flawless, with a minor hiccup in the grounding (no 10MM Hex bolt under the CF roof) - but a quick trip to Home Depot fixed that. Works like a charm.
Only a day under my belt with my V1 and I've already been spotting "bogeys" before they ever see me. Nice.
