It's Simple, it works, well done. I'd like to see how this evolves over time, maybe you can keep track of that and publish some nice graphs.
On a sidenote, i am amazed how well Hetzner is doing. They always had a good reputation back in the days, but i feel they are missing out on a lot of business. They really lack the features and comfort of, for example, DigitalOcean or Linode.
