LaserLyte - again

I don't recall if I mentioned this or not, but after LaserLyte replaced the defective Rear Sight Laser on my M&P, I took it to the range, where it promptly began having issues and has since failed completely. I bought a set of TruGlo TFO night sights and the slide is at the fun shop now having those installed.

I also decided it was time to mention the issue to LaserLyte, and sent them the following via their "contact us" link:

Back in May of this year I purchased a S&W M&P9 with your RSL. The original unit was defective and was replaced by your company (quickly and efficiently, much appreciated) with a new RSL. I installed that and some time later took the pistol to the range. Unfortunately, the new RSL had significant issues as well. Initially it would cycle modes with each shot - from off to steady to flash to off etc. Eventually the switch failed completely and the laser will not turn on at all.

At this point I can only assume one of two things: a bad lot of switches, or the switch was never up to the demand of recoil (115gr Winchester 9mm, btw) and the motion of a slide. I have since purchased and installed a set of tritium night sights which are meeting my needs nicely.

I'm not sure what you can actually do about it at this point. I have no confidence in the RSL arrangement, and feel that another replacement would be a waste of your money and my time, as I wouldn't install it on the pistol. I just felt you should know that there is a clear issue with the product. If you have any questions, suggestions, ideas, or requests, I'm open.
Thanks!
(The original RMA was ####, if you care to look into that one as well.)

We'll what, if anything, they choose to do, and I'll post results here.
