I got this for my Taurus 709 slim today and mounted it in about 5 minutes and took another 5 to get it sighted in (according to the iron sights). Haven't taken to the range yet to fine tune the sight, but can't wait. Laser is very easy to see indoors and in low-light conditions, and the night sight seems to also work very well (tried it out in a dark room). I have a tritium front sight, and the rear one when activated works very well with it. Overall wonderful product in my opinion.
Pros: easy to install and set up
Cons: not very good for use in daylight, but not it's intended purpose
