application of the product is irrelevent, it's still the same premise, you bought a faulty product, sent it to the manufacturer, and they fixed it free of charge, but because you disagree with the manner in which they fixed it, you don't even want to give the product a chance.
I recently purchased a Ruger SR45. the hillbilly I bought it from tried a whole bunch of home gunsmithing techniques to make it better and completely destroyed the handguns reliability. I had to play phone tag with Ruger for weeks to set up an RMA, and finally just mailed it off two days ago. I am not the happiest with Ruger CS right now, and because I was open with the fact that I am not the original owner of the firearm, I am not certain that they will even fix it, no less fix it for no charge, but you can rest assure that no matter how upset I am with Ruger, the jerk and liar I bought it from, or the handgun, I am damn sure going to at least test to to see if their service corrected the issue before making the decision to sell it.
