When we bought Elyse in 2013, I didn't think I'd ever use it, but I do !
With just two on the boat it doesn't seem justified, but with 4 I have used it a lot.
With just two on the boat, we wash dishes by hand and put them in the dishwasher to drip dry.
This works really well at sea.
After a couple of weeks we run it to drain the water out of it.
