Customer Service is Awesome!!
I had an issue with the wrong item being sent to me. It looked like a previous dishonest customer returned a $40 red dot sight from Amazon in the Holosun box and it was sent to me inadvertently. I contacted Optics Planet they asked for pics and then promptly send out a replacement.
The quality of this red dot is very good and the ease of setup is awesome. The price point on the sight is very good compared to to the features it has over more expense sights.
