My 415+ had the famous C2000 issue where the timing signal wouldn’t be sufficiently pulled down/up. This lead to freezes and ultimately to a non-booting device. And that happened like 3 months out of warranty. The only “support” Synology offered was in helping me selecting a new device to buy.

And they clearly knew how to fix it at this point as the support in other countries DID fix people’s devices. Luckily, the Internet did its thing and I was able to solder in the missing resistor myself.

But that was the moment where I’ve decided that the next device won’t be a Synology again.
