It is an extremely durable optic that, of the available options, has the least fucks to give about environmental factors.
It uses a battery that has about 1/5 of the power of a 2032 series battery so battery life on useful settings (seemingly for most people's eyes) is significantly shorter than on the RMR. Battery changes on the ACRO are extremely easy to perform and can easily be done preemptively on a schedule. You can even keep a spare battery in the back grip space on the Glock.
The biggest day-to-day issue I deal with is adjusting the brightness setting for the conditions. In the day I keep it on 8 or 9 if I'm carrying it, or at max if I'm using it outdoors on the range. I dial it back to 6 at night because my go-to gun is a shotgun rather than the G17 the ACRO is mounted to.
I prefer it to the RMR.
But at this point in the game picking the right RDS for you is about picking the set of issues you want to deal with. The ACRO's battery life is pretty easy to deal with and the batteries to feed it even if you keep it dialed up really high is less than most people are paying for a yearly Netflix subscription.
