What an utter disappointment !!! - LaserMax CenterFire Gripsense Light & Laser

Ordered this lasermax green laser with light combo. Received it from Optics Planet and received it in 4 days. Read the entire instruction manual watch the instruction video that they have on YouTube then proceeded to install the laser on my Smith & Wesson M&P 9mm. Remove the battery cover installed the batteries and lo and behold the battery cover would not stay on the three little tabs that hold the cover on we're all broke. I called opticsplanet the customer service agent told me that this was her third call on this product in a week having the same issues. Extremely disappointed so I'm returning the product and going to put in for an exchange I don't feel confident that the new one that they're going to be sending me is going to be any better but I'm going to give it a try. Stay tuned will update you on the progress and how it works once I received my replacement unit.
