Product review (2 stars): Fine if you only want to use cold water
So it's to be used either by hooking it up to a sink faucet using the cold water inlet on the back of the machine, or it is to be used by hooking both inlets on the back of the machine to the hot/cold outlets from water hookups you might have in your home. The house I rent has the hot/cold outlets, so I chose to hook it up as a regular washer.

Well, the hot water inlet doesn't work. When the machine should be pulling in hot water, it only buzzes. If I switch hoses, the hot water will come in the cold water inlet, but the cold water will not come in the hot water inlet. So it's the hot water inlet on the machine that is the problem.

I emailed customer service, and I posted a question about this in the Questions section of the Amazon page for this item. The reply?

HOT WATER MAY DAMAGE THE MACHINE, MAY DAMAGE YOUR CLOTHES, MAY BURN YOU.

What kind of response is that?

So I use an adapter to combine the hot/cold water outlets into the one cold-water inlet, and I'll live with it.

But I certainly don't recommend anyone else to buy it.
