They have fairly good prices for small VPS, something like €1-2 and I cannot complain. Perfect for some small self hosting. I cannot comment on their more performant boxes.

1&1 is kind of typical telco, with all the shady stuff and contracts. DSL from them is without any issues. Mobile is kind of problematic, it was fine for past 3-4 years but with their “Fancy 5G net up to 300mbps” has pretty shit so far. Last week I was abroad and my sim would not connect at all. Contacted them via online chat and they said to call them… They fixed it after like 20h
