There are two things I don't do when I do business with a company - accept second rate quality, and second chances. They failed on both accords.
YMMV - if you're trusting, be my guest...they've been in business for a long time, so they must occasionally manage to bumble something right, hopefully more often than not.
They screwed up with my stuff to a level that's pretty unreasonable - any idiot could have looked at the zipper before they ripped it out and figured which way it goes, or could've tested the suit afterwards and seen clearly that it would've leaked. Drysuit repair isn't rocket science. The nail in the coffin for them is that they then didn't do anything to make it right. As a side note, I'm also not pleased with the quality of the "fixed" zipper replacement, either. It's already starting to go on me, and I've been pretty light on the suit this last year and a half, as I've been busy with activities that preclude diving, and have maybe 100 dives on it since, which is pretty low.
That kind of behavior put KME on my proverbial "never again" list. I've got a better term for that list, but this is a "family" BBS. What reason would I have to possibly go back, especially when I have found an upright, reliable, high quality vendor who does better work and costs less?
