I have way too many Netcup products already; I wish I had some reasons to buy more I have to renew a couple of them in May as well.
Almost 1 year and a half in, top notch services so far. Contrary to some reports I’ve seen elsewhere, I’ve enough nines to fill an auditorium and 0 or close to 0 steal, even on non-root products. As already noted multiple times, be aware of what you’re going to buy beforehand: they assume you’re aware of their ToS and of German Laws in general.
