Costly? Catastrophic, surely?

It will be interesting to see which pump they use as a replacement (where users select that option).
As an aside (and to settle a "discussion" here) ... am I right in saying that the basis of the Colleague was the
Danby pump (made in the UK)? Did Baxter buy Danby?
The Colleague saga is a great pity, I reckon. The design was certainly advanced - but just brought to market a bit early, I guess.

But (lastly) what is the current state of play with the Colleagues ... anyone care to summarise the outstanding technical problems (if any)?
