Failure to launch - Crimson Trace 1911 Master Series Full-Size Laser Grip

I had this laser grip on my Kimber 1911 5-inch. After a year in the lockbox under my bed, I went to shoot it at the range (I have various handguns and take them all for a spin. Most of them have Crimson Trace grips. The grips on my Sig Sauer P232 failed after two years and my full size Kimber has failed in about the same time period. I made certain the batteries were new and fresh but to no avail.

I think the quality of Crimson Trace has significantly decreased over the last 3 to 5 years. Although I have purchased 5 of their products, I believe prices (and technology) are going to result in me looking elsewhere for my laser products.
