I'm also in the same boat of regret, but for other reasons. Their support team is beyond awful. I purchased an H2S AMS combo just shy of two months ago (mostly because I saw it being praised by HNers a while back) and found out recently that the AMS they've sent me is defective. It's been truly a bizarre experience trying to deal with customer support. They told me to disassemble the AMS and swap a couple of modules that they mailed me. I did, provided them evidence that I did, and provided evidence that it didn't fix the problem. Their response was to claim that I didn't actually swap the modules and that because of that my warranty no longer applies, and then they said they'd give me a free roll of filament for my troubles (lol). At that point I began the process of invoking the consumer protections afforded to me. Called my credit card company and opened a dispute, invoked Massachusetts law M.G.L. c. 93A, and I'm about to contact my AG.
It's a shame they're going in such an anti-consumer direction, both with their gaslighting customer support and the lawfare against Orca.
Just wanna say, I appreciate you going through the effort. Please share your story as it progresses!
The Magnuson-Moss Warranty Act is your friend. Furthermore, the idea that you could be expected to perform technical labor to repair something is ridiculous: grandma is protected, too, and this type of service falls far outside the scope of what is reasonable.
