We have had similar experiences to those already mentioned .
However having took these issues up with our local rep (resulting in an on site meeting with the MD here) things are begining to improve.
Not so much around reliability of existing kit (yet to resolve completely) but more in the way of recompense for encountered issues to date.
Hopefully the future plans (ala Spacelabs)will bring more good news.
Trust this info. may help others in a similar position.
