Interested in the tru dot, but tempted to wait for elcan hco or the Hartman mh1.  How have the tru dots been holding up?

this is sort of timely for me. also interested.

No long term reviews?

I owned several Mepro RDS' before I switched to the Trijicon MRO. For the couple of years that I owned them, the only problems I experienced were:
1) Reticle flickering during recoil, because I didn't have the battery cap fully tightened.
2) Control knob occasionally rotating to the 'off' position from rubbing against my gear during transitions.
HTH...

I have 3 of them and never had any problems with any of them. Battery lasts about a year depending on the battery brand. The max dot brightness is fine even on very bright days during summer. The flickering dot during recoil means low battery.

I ran one pretty hard for a while. Bought it when they were first imported to the US. I had zero issues.

I have 3 of them and have had one of them for close to 2 years. This one is on a rifle that I love to shoot. It probably has 3000-4000 rounds on it.

No complaints. I have seen the complaints about reticle brightness but not sure what people expect. In bright sun the reticle is plenty visible on high. This is the case for all 3 units.

One of my units I bought used and has the metal hood. The other 2 have the plastic hood.

The only negative I can say is the mount is not removable so you can't run an aftermarket mount like LaRue.

I've had one going on a year now.

My impressions thus far..

Pros:
Love the EoTech like viewing window, switched to the RDS when they pooped in their hat last year.
Window is crystal clear with little to no noticeable tinting.
AA battery is easy to change if needed, still haven't had the need though.
Dot seems smaller than the Aim Point 2 moa dot, Meprolight says theirs is 1.8 moa I believe.
Mount works fine though I haven't removed it since mounting it so I don't know how well it returns to zero.
Motion sensor has worked flawless

Cons:
Mount studs stick too far out and catch on gear, not bad but enough to irritate.
The RDS is slightly on the heavy side compared micros or even a PRO in an Larue mount. "feel wise" I've never weighed them side by side.
Feels like there should be one more brightness setting on the high side.    

I wont be getting rid of my Aimpoints but I don't see the RDS going anywhere either, both are brick house solid.
