Your cheapest plan offers 512MB of RAM for 5 Euros a month. There's well over 5 competitors who can get you quadruple that amount of RAM and maybe even double the storage for half that price per month. This is due to renting out space at datacenters, no? I'm no hosting expert.
Thanks for looking into the service. We're certainly not the cheapest in terms of pricing but I would also warn against using RAM prices as the sole way to gauge a service.
To drive low prices a lot of VPS providers tend to have a very liberal way of playing with overcommit, which we don't do. The same goes for CPU.
Our instances should be considered to higher-end families such as the C3 and here you'll see we're playing in the same field in terms of prices.
Many of our clients choose us for performance (IOPS, memory guarantees, etc...), and our geographic and legal situation (no connection to 5 eyes countries, strong privacy laws).
