i bought this for my camper van and i am very happy with it, runs off my 1000watt pure sine wave inverter and brews up a lovely real coffee. The insulated cup is large and keeps the coffee hot longer. Only gripe if you can call it that is cleaning the filter uses a bit of water when camping as you have to run it under a tap, when camping the tap doesnt have the same power to clean it. I know if your at home it's easy to run under the tap. I still love it and no more instant coffee that tastes naff while i'm camping (",)
