The Varia VS4 is an all-purpose 53mm single-dose grinder with a set of stainless steel conical burrs and a variable speed motor that can operate at speeds between 150 and 300 RPM. Its incredibly low retention guarantees that you brew with the freshest coffee possible while the higher RPM reduces fines for greater clarit
Based on what I've seen online, I am giving this grinder an opportunity to replace my Niche grinder because of its different speeds and near-zero retention. So far, the hopper has clogged maybe 20% of the time I've used it, which left less than a full shot ground until I realized it on my next usage of the grinder. Of course, it's caused me to change my behavior and look at the hopper every time now. All in all, it seems to do a very good job of grinding. I've only used the slowest speed of 150. I do like the auto shutoff function, and I do like the idea that I could add beans to the hopper more slowly if I wanted to, which I cannot do in my Niche.

Minimal retention
This grinder has one of the characteristics that I was looking for in other grinders, the retention is minimal. I can enjoy more of my coffee because it doesn't stay trapped inside. The grinder process is fast and it can be adjusted easily.
