Amazing red dot - Vortex Defender-CCW 1x25mm Reflex Red Dot Sight

The red dot has a small profile and conceals easily on my TX22C, Glock 27, and P17. The shake awake is good. The auto shutoff after 10 min is a huge upgrade from the previous 14 hour time. The dot gets very bright on the highest settings, and almost too bright even in the sun. Turrets are not clicky at all, are sort of mushy and hard to "feel". But, I was able to sight in within about 7 shots with no problems. I think smaller red dots all have pretty much the same turret feel though. I would definitely purchase again and recommend to anyone on the fence about this one.

On a side note:
I bought 2 of these at the same time, and I am pretty sure one of them was used. The turrets has some marring and the up button was not functioning properly. Rather than send it back to OP and have to wait 2-4 weeks to get it replaced, I got in touch with Vortex directly. Vortex had me send it in and they verified the issues and are replacing it 100% as well as covered all shipping to and from. The lifetime warranty is what encouraged me to purchase this over the 507K. The warranty did not disappoint.
