I had a completely different experience when I sent my ML16803 in for a checkup after I suspected problems with it. FLI bent over backwards to test it and in the end they replaced a board just to make 100% sure that there wasn't a problem.
John, I do not think your personal experience is relevant in the context of this thread. You are a high-profile figure in the world of astro-imaging, so I'm not surprised one bit FLI did bend over backwards to fix your camera. Question is, what is an average Joe to expect.
To illustrate... Regular photography market is undergoing massive contraction for more than three years now, and Nikon just announced it stops support of all 15 authorized repair centers in the US, leaving only two of their own. Nikon users' support hadn't been great lately, to say the least, now it might as well be total cr@p. Details can be found in Thom Hogan's article. Thom, personally, sees none of it; this is what he had to say:
I've had very good service from NikonUSA. They know who I am and how many of you read what I write: I'm pretty sure that my servicings get special handling within Melville.
I also remember that when the front of a Hasselblad lens owned by Michael Reichmann fell off (literally!) during Michael's trip to Africa, Hasselblad immediately flew a replacement there (yes, to Africa)! That lens BTW was less expensive then ML16200; a few grands. Now, not every photographer knew who Michael was (and when he passed away several years ago many guys at DPReview were asking why the hell are there threads about it and what's the big deal), but those who shot MF did. So yeah, while both Hasselblad's QA and service were pretty crappy already, they did bend over for MR. These days, they are a pale shadow of the company that sent their cameras to the Moon, a niche player owned by DJI (drone manufacturer).
Frankly, I do not even think that GeneralT001's eventual experience will be telling -- after this exposure at CN, as I bet FLI guys read CN. I would.
Finally, all these anecdotes aside, I was very surprised to learn FLI provides only one year of warranty period. This is not what I'd expect from a premium manufacturer, at all. Especially given that QHY and ZWO give two-year warranties (though QHY clarifies that Kodak/OnSemi sensors are covered by one year manufacturer's warranty, while Sony sensors are covered for two years; everything else in the camera, save USB cables, is subject to two-year warranty; I wasn't able to find details of ZWO warranty policy).
