Very sad outcome.
Although i've been in quite a few, personally, I dont like them much as I feel they rely on on too many parts which could go wrong, go wrong.
Maintenance demands seem far hight than what i'd prefer.
Simple things generally seem more reliable to me.
That's just my personal feelings.
Back when I worked in UK for an electronics firm, I was involved in the final test and inspection for many huge control panels built for the British Navy.
All the wiring was pink. Thick bundles of it!
Can you imagine what a headache that was to sort out all the wiring mistakes from the factory floor?
It's no wonder i'm a bit nutty!
It must be very, very expensive. A doctor at a medical centre wanted to charge me $90 for a 2 or 3 second burst of it to freeze a little something off the back of my hand.
I had to laugh, and then told him what it costs per litre. then went elsewhere and they did it for free.
