I bought a countertop dishwasher that works perfectly fine but didn't end up having space for in my own kitchen. Cleans much better than you'd think and is basically the size of half a normal dishwasher (1 tray instead of 2). Hooks right up to a normal faucet with a special faucet adapter that is all included. The faucet adapter is a duel inlet/drain all in one. I'm bummed it doesn't fit under my kitchen cabinets but what can you do. I know many people use them for RVs as well. Cost close to $300 new and I only ran this one twice.
Comes with the hosing, adapter, instruction manual, quick connection installation guide, and my experience hooking it up.
