Does anyone have any more to add (latest update, recent news) on this one?

How are the Nimbus' usually maintained:-
1) In-house
2) In-house (1st.line only)
3) On contract with Huntleigh (Arjo, whomever)
4) On contract with a third-party service provider ... ?
In case of option 1) ... what test kit
etc. is needed?
