Colleagues are still crap.
They are overly complex, fiddly to repair, they allow fluid ingress at every joint, physically big and heavy. Even something as routine as battery changing needs extreme care and have dodgy display drivers.
This is nearly 2003, pumps should have evolved into very simple devices in terms of maintenance and use. I thought we were almost there with the Danby DCR even with all its faults.
Prolific IV devices of this nature should be much simpler, extremely robust, practically immersible, physically smaller, with due consideration given to the environment that they are used in. The Colleague doesn't cut it any of these ways. :p
