Motion activated red dot sights

Curious. Why would you want a motion activated sight when a Trijicon RMR that is always on and self adjusts to outside light can run more than a year on it's battery. Seems like just something more to go wrong in a sight to have to rely on an extra sensor.

Don't know about the others, but the Romeo also has on/off buttons as a backup, so now it's a huge advantage as you end up with a battery life that is multiple years.
 
For me the reasons are simple. I like different sights for different reasons.

The Meprolight had a larger sight picture than a Trij RMR, and works very well with a flip-to-the-side 3X magnifier. It is night vision compatable, has a 10,000 hour battery life on a single AA battery, and I can find a battery at almost any store.

The Vortex Strikefire II has red/green reticles. The green works better with my eyes especially on the lowest light setting for dark environments

The Holosun has a choice of reticles and solar charging that gives me a lot of options.

The reason I like the auto on/off of the Mepro and Holosun is that I always forget to turn them off. I put them in a case or in the safe with the sight still on or I will just put the cover on the optic to keep dust and debris off and not realize it is still on. The I pull it out, take it somewhere and the sight is dead. I carry several batteries along in my range bag because of this.

With the newer sights and auto on/off, I haven't changed a battery yet.
 
Interesting answers. I was looking at the sight being used on your EDC gun or the rifle you would grab as a self defense weapon. For just range use I can see any of them working. For an EDC or emergency self defense weapon having to turn the sight on after being completely off or hope it wakes up seems a none starter. Simpler is better. Way to much stuff going on in a threatening situation to have to remember to turn the sight on or trust it to turn on. I am using Trijicon RMR's, so never a worry about being on, it is always on and if I change the batteries once a year, still an easy solution.

Cost. I picked up the Romeo5 for a third of the RMR cost. I know it's probably not comparable quality wise, but for my needs it should work. It also co-witnesses with my iron sights. This video sold me on the Romeo5. So far the motion sensor has operated perfectly.

I like the motion activation for a self defense gun. On non-self defense optics I usually remove the batteries when not in use. It is a bit of a hassle, but I've had more than a few devices ruined by leaking batteries. Another reason I don't want to spend to much is accidentally damaging. While the more expensive sights usually hold up better to abuse I would try to take better care of them knowing what they cost.
 
My understanding and using actually using them...if you wear a motion activated red dot, on your hip and you move at all, the sight will stay on. Problem arises when you actually need the sight the battery may well be dead, since basically it is always on.

I carried a Delta Point Pro equipped Glock as a duty weapon. 10 hour shifts. I left the sight on after shift because I had on call. Worked nights so it was maybe 3/4 brightness setting.
I replaced the battery after 4 months, not because it died but because I figured I should as a preventive maintenance.

Pretty much what Flash said.

Romeo 5 can be purch'd for well under $200 retail - battery life is 50K hours = 5.7 years

I prefer Romeo 5X - runs on AAA battery instead of button cell or CR2 like other dots I own - 5XDR has a switchable reticle, but I found the 5X best for my needs.

Three of us in my weekly shooting group have these and we've had no problems whatsoever. They work well.
 
I have a shield RMS on one of my pistols. Its an "ALWAYS ON" reflex and they advertise 2 years battery life or something like that. I left it in direct light 24/7 and it started to lose brightness at 6 months so I have a pretty good baseline on when to swap batteries. It has a side load battery tray that you can pop open a tiny bit to use as an off switch for storage. I was thinking the same as some of the previous posters that a motion activated dot on a carry gun will be on most of the time anyway, and thats one more complication in the electronics. the RMS (updated Jpoint) is somewhat new and I took a chance but so far so good on about a year and 2K rounds. They advertise a great warranty as well.

Products designed and manufactured by Shield carry a two year warranty on materials and workmanship.
They posted on both facebook and instagram during SHOT that they changed their warranty to 7 years on defects, and lifetime $75 replacement/repair fee for accidental damage of any kind.

Just a bonus though. I bought it because its super low and compact.

But it won't be on most of the time. An always on is on 24/7/365

A motion activated is essentially almost always on when you're using it. The rest of the time it's off. Most people I know don't shoot them more often than once a week for a couple of hours, so 2 or 3 hours of on time compared to 168 hours of on time for the always on reflex.

Big difference
