The Bibo is better than boiling water in a kettle. It's instant hot and cold water which tastes better than the tap water. It has given us a few problems in the past but all repairs have been quick and without any cost. The instructions for cleaning the hot tank could be better. (Note 8. in the preparation) I followed the instructions and the cleaning solution frothed up and overflowed. This caused a fault. I now turn the water off at the back of the Bibo and it stops the water flowing back into the tank. I then turn the water back on after the solution has been put in. The outside of the nozzle builds up with scale and appears to be rusty. The staff at Bibo are very friendly and efficient.
