I have one and I set my wife up with one as well. Love it wouldn't think of not having one. I like the functionality and streamline it gives eliminating a hose. One of the overlooked highlights is the large easy to use buttons and the quick connect is much larger than others which makes it easy even with gloves. as far as care, I rinse and flush it well after each dive never had a problem. One advice is I ask the repair tech to detune it a bit so it doesn't freeflow on the surface, only happened once luckily its an easy adjustment.
