Agreed on the topic of ergonomics. The original Grids was a lot bigger than it needed to be in my opinion, but these micro clones that aim to be literally as small as possible overshoot the mark.

uGrids is by far the "u" module that is least impacted by the downsizing (maybe tied with uO_C) , as there was a lot of room on the original. The main thing to consider is if you like the feel of the larger knobs or not.
