Crimson trace for my sp101 - Crimson Trace LaserGrip Polymer Laser Sight Grip Fits Glock 4th Gen SubCompact Handguns

I purchased a crimson trace for my ruger in 2011 and only used it maybe 30 or 40 rounds over the past 9 years. I pulled it out last week and tried to use it and it did not work. I replaced batteries 4 times and still nothing. I contacted crimson trace and they said the best they could do was to take 50% off a new one. They did not want me to send it back to troubleshoot or nothing. It cost me 240.00 so I am not inclined to spend more money on a product that the manufacturer will not stand behind. Just my opinion.
