### ⭐⭐⭐⭐⭐ it works.

### ⭐⭐⭐⭐⭐ It’s a good product
*by D***G on October 12, 2025*

It’s easy to use. The light was bright and accurate.

### ⭐⭐⭐⭐ Solid product, easy to use, horrible batteries.
*by N***D on March 1, 2020*

Overall a solid product, easy to use. Just unscrew the back, pop the batteries in and it's on and working. However, here is where I drop one star from my rating. I tested it at home and everything worked fine bright laser, fits in the bore of my rifle everything seems good. I had the batteries in the sight for less than 60 seconds to test it's functionality. Promptly removed the batteries and was excited to get to the range to sight in my rifle the next day. Next day I get to the range, setup the rifle, get the bore sight setup, and in the bore of my rifle. Before I could get my red dot turned on the batteries were dead in the bore site. I removed the site, and batteries, replaced them thinking I maybe put them in wrong, nope batteries were dead as a doornail. Wasted trip to the range as I didn't have spares with me. So do yourself a favor and buy extra LR41 batteries with this sight and save yourself a wasted trip to the range like I did.
