All in all, I am quite satisfied of all the hardware I bought across all these years. Computers, disks, memory, etc. All that geekery is reasonably good and the epic failures are rare. And even when an epic failure happens, the manufacturer is usually smart enough to issue a recall and free replacement even if the 2 years period after purchase is over. (e.g. Apple with the graphics card failure that hit so many older MBPs a while ago). In two occasions only, the manufacturer did show a pretty bad behaviour:

  1. the first case was years ago, when my Sony Vaio laptop was hit by the infamous "inverted trackpad" bug. In short, Sony avoided a 3 cents' expense isolating the trackpad electrical system from the metal case of its Vaio line and the trackpad was inverting the x axis, sometimes the y axis, sometimes both... Totally unusable of course. Millions of Sony laptops were hit by the issue. I had to shout on the phone to obtain, a few months after purchase of the most expensive Vaio at that time, a replacement of my computer. Cured me from Sony computers forever.

  2. and the most recent case, happening right now, is my Synology DS412+ NAS server. In short, it's been plagued by a zillion of issues, all severe since let's say day 50. But every time I was ready to send back the NAS to Synology, the support was asking me to try something (or giving that hint on their fora) that led to a normal reboot of the unit despite of motherboard warnings. On reboot, the warnings were going away... A few days ago, my DS412+ stopped working, with a forever-blinking blue led light. Motherboard failure, again and again and again.
    The Web is full of people explaining how bad the DS*12 series is, and the reports of motherboard failures are absolutely everywhere. They even issued a press release but never contacted customers, eh.
    Unlike Apple, Synology refused today to change my motherboard. And it took a week, and tweets added to my email, to eventually obtain that response from them. To someone else, they proposed to buy a new motherboard for $395, so 80% of the unit's price (yes, expensive!). They can rot in hell, of course.
    So Synology, it's a crappy support for buggy motherboards sold for an extremely high price. If you're lucky with your motherboard, you will never see a problem. If like me you bought a buggy unit shipped buggy, Synology will refuse responsibility after the end of the guarantee period. And during it, you'll need to ship the unit at your own expense.
    Synology's DSM is cool, their units are cool. But they're not reliable enough and the way Synology considers customers who paid a premium price is just a total shame and not in line with 2016 industry's standards, and most probably the French law here.
    Conclusion: avoid Synology as much as you can. You've been warned.
