I got the Vermona Modular qMI2 MIDI-interface to have a poly/4*mono +clock in my eurorack. While the module was functionally pretty much exactly what I was expecting, the convenience of the module really surprised me: Setting up the midi channels, groupings, clock and modulation sources are really fast thanks to all the information printed on the module and the good design of the module.
The only dumb thign about the module was the fact that the screws that came with the module were too short to be used with the washers that came with the module(tried in tiptop mantis case and a doepfer a-100 case).
