The red dot sight seems to be a good value. The dot is crisp and clear for me, and it has a good range of brightness levels. I had previously owned a Burris XTS-135 (which goes for $200), and I prefer this sight over the Burris. Battery life is comparable to the Burris/SPOT. Downsides - The "tree style" mount that comes with it is a piece of junk, and the instruction sheet is poor and it seems to be written for a different model.
