Homey don't play batteries, so the only ESD or dot sight I partake of any more is the Trijicon RMR-DI. Or the Leupold 1x14 Prismatic (arguable whether it's an ESD / dot sight). Something that works with batteries, or with or without batteries.
I agree with Dakotapotts - get a 1-4ish scope. The best budget-y illuminated one by far, in my opinion is the Burris MTAC 1-4x24 (at least as of the last time I researched it as of a few years ago), because even if the batteries fail, the reticle is still there! On 1x with the large outer ring, it works as a dot sight (ESD) or if you like even an OEG with a front lens cover. But on 1 or any power, the center reticle can be used whether the batteries crap out or not. To find that same feature in a scope with a true 1x on the low end AND a large ring or dot, AND still has the ring & reticle when the battery craps out, you have to jump from $300 for the Burris, all the way to over $1,000, unless there's something new out there.
But sure, a TRS25 would be "ok" on it, and get you out as far as you'd ever actually use it on large game or anti-personnel sized targets - 75 to 100 yards. I wouldn't pay the $70 or $80 they cost now, but if someone gave me one, I'd stick it on a rimfire or fun gun like that. I can't see paying good money - even a small amount - for something which is battery-reliant, which is anti-thetical to a firearm's purpose - reliable. Only exception would be Aimpoint with 50K hours battery life or possibly the new Trijicon.
Generally speaking, dot sights are JUNK, and their value goes down faster than PK Subban in a playoff game. Buy quality (i.e. Trijicon or Aimpoint) or forget it - IMO. And I've tried a few, believe me. And if you can't afford that quality in an ESD, stick to a scope which will give you a better value - a Nikon, Burris, Leupold, Vortex, or Bushnell Elite.
