OK, I love the Cloud as much as the rest of you but I have to say I wouldn't buy one right now from any existing stock. Its almost certain to be from the problem source. All these Cloud+ failures at or about the same time seems pretty indicative of a more widespread problem.
Now I have the luxury of saying that, because although I've just had a one month old Cloud+ fail I still have my original Cloud that's now on month 11. I had promised to sell it to a friend after giveing the new Cloud+ a month or so shakedown. When it failed a month to the day I told him sorry, but I'm keeping my original. I bought the upgrade for it a while back, but haven't gotten around to sending it in...thank goodness.
One odd thing I've noticed is the Cloud+ gong seems to have a smaller ID since all my ElBs are now loose in my original Cloud. Its actually kind of a problem as I favor using my Cloud inverted on my Matrix Ion and a couple of times the ELBs have slipped out and dropped down into the water. But as problems go, not a biggie. At least I still have a working Cloud
