Hey, for anyone looking at these units, I wanted to post my initial thoughts. First, Tactical Imports did a great job of shipping it quickly, and I got it fast, no complaints there.
The unit itself is very compact, seems well built and sturdy. I'll add the rubber armour later. The battery inside the unit when it arrived was 100% dead, and the unit would not power on, even in bright indoor lights. That concerned me, I was hoping the solar cell would run the unit even with a dead battery, but it would not at least in the conditions I had. They were compact flourescents, so its possible they don't generate enough solar power for the unit.
There was a fresh battery included in the package (only one was promised in the marketing, so given the one inside was dead that was great) I switched to that one, and it worked fine. When the unit powered on though, the automated brightness on the red dot was very low, the dot was barely visible. I was able to manually increase it and it works fine, but I'm wondering if the automatic brightness function also didn't like the compact flourescents. If that is the case, this function may not work at indoor ranges, nor would it be effective in an actual tactical environment when transitioning from outside to indoors with flourescent lighting. I'll be doing more testing of this issue later on to confirm my first impressions.
I haven't yet mounted this unit as it is for a build that isn't completed yet, but I wish these units had the slide lock feature for locking them in place on a rail. I'll be investigating if that can be purchased separately at the same time as the rubber armour. I can see the unit sliding on the rail if there is an impact of some sort without the slide lock.
