Coincidentally, I can tell a story about computer keyboards, in this case Ultra Classic from Unicomp. Their keyboards use the same technology as the legendary IBM Model M keyboard (I have one that was produced in 1985 and it's still my favourite keyboard, use it almost every day). I even heard (though don't know if it's true) that Unicomp produced branded Model M's for a while.

But even though the Unicomp has mechanics equal or comparable to the Model M, they have serious issues with the molding process. In spite of warnings on various internet forums, I got a slightly used keyboard from Ebay and it quickly developped issues with the space bar (the mold is so bad that the key had too much friction).

They have been nice enough to send a new space bar, but sure enough the new one has a huge dent on it (only affecting looks this time). Also, I'm left with a deformed spring (I thought I'd been careful but...). Now being offered RMA and being requested to send it from Europe to USA. Again, friendly service, but I'd rather have quality.

I don't know anything about molding, but it seems to be that some process knowledge gets lost over time, as demand decreases. (Or maybe the machines need to get serviced?)

UPDATE, found an introduction an youtube and loved it. Submission, https://news.ycombinator.com/item?id=17381697
