I bought a Venus Water heater, 3 litres capacity 2 years ago. Got a warranty of 10 years for a very cheap price as compared to other water heaters available in the market.
Since 2 years its performing in an amazing way, it consumes very less electricity.
It heats the water very fast. The product is really a value for money. The size and the design is very compact and it get fitted in a small space. The look of the product is also very good.
