For such a small formfactor the Klavis Two Bits packs a lot of features and versatility.
It has two sections for generating logic output based on two inputs. It has a variety of different algorithms for the logic and creates two outputs with the second one being inverted.
This allows for creating logic based rhythm patterns, ducking effects, generative patterns and so much more!
With it being so streamlined, I find it a lot easier to understand than some other logic modules (for examples Maths, which is wonderful, but might feel a bit intimidating especially if you are just starting out in modular).
The build quality is great - I love it. And lately I've been using it a lot to enhance the sensitivity and expression of the Doepfer A-178.
