I wish Kambrook had a customer comments page on its website because this is where belongs.
The Kambrook KHV hand held Vacuum is a load of rubbish. Don't buy it. it is badly designed, it should 'suck' and in one way it does, but not as a vacuum. I have used it three times and have thrown it away.

Worst electric rice cooker I have ever had. bought this model because it looked good but immediately realised that it was a bad choice. Cooking rice was never clumsier.
The lid gets messy with the starch and the area around the cooker will be spilled with the rice starch and the cap will be filled with the starch and cleaning the cooker takes more time than cooking. There is no proper vent for the steam and the lid is attached to the main unit and this makes cleaning hard. Would never buy this cooker again.
