Love the shake to wake and only took minutes to zero in at 10 yards. It works as advertised. Shake awake seems good.
Rfx25 uses the doctor footprint and can be directly mounted on your weapon. The qd mount is excellent, i really like qd and this one is one of the best i've used so far.
The rfx series is a good edc option. The instant on feature is now considered by me to be a must have feature, far exceeds my other dots red dot sites, from burris and vortex. Has nv compatible mode.
Tried the used battery again, nothing. Even on the maximum brightness and with a new battery, it's just not enough. Did not hold zero either.
Easy install with perfect fitment. Working great so far. Zeroed and holding. Clear glass and red dot.
