"Companies tell me there is a 1% failure rate within the eurorack industry, however, the failure rate in my studio is almost 40%. No lie....."
If the failure rate in my studio was 40% or anything even remotely close to that, I would look into the possibility that there was an issue with my studio, just saying.....I have a fairly big system, and have turned over a fair number of modules while building it, but off the top of my head I can only recall having to make a video for a manufacturer once. I think the failure rate I've experienced might even be < 1%. This is across two different homes, as I've had to move once after my system was largely built. So if you're having to make videos all the time, that should ring some alarm bells.
Regarding Instruo in particular, I have a few of their modules, so far they've all worked fine. I remember them being slow to put out manuals for some of their stuff in their earlier days, but that's really the only negative thing I can think of to say.
