Disappointed - Crimson Trace Master Series Lasergrip w/ Green Laser for 1911

I was very disappointed in my recent purchase of a Crimson Trace laser. I had ordered two. I had to send back because it wasn't working. I had the same experience with the second one. I do not blame Optics Planet for this at all. I checked with Crimson Trace, and they have had numerous reports of the same issue. I am however very disappointed in the response, or I should say non-response, from customer service this time. For two days running I have left my phone number with the assurance that my call would be returned in the order it was received. I have not received a call from them. I find this very disappointing and unusual, because my experience in the past with Optics Planets customer service has been very positive. I'm very disappointed.
