I am using Blue Star Water Dispenser Three Tap for over a year now. Bought it from electronics retailor in raviwar peth, pune for 8900 rupees.
Its design is perfect for business usage. I have kept this dispenser in my office. It has option to have normal, cold and hot water. Hot water tap has child lock button. Its speed of making water hot or cold is amazingily fast. Machine which I bought is having enough space to store something to keep in warm place.
