We purchased our hot tub recently from the Hot tub centre in Norwich. They had an amazing 15 tubs on display, which gave us a great selection to choose from. We decided to have the new spa boy system, so that we can monitor and adjust if necessary our chemical levels in the tub from wherever we are in the world. This was a great selling point for us, as we're often away, and can monitor if the kids are in it!! Thanks to Kevin and staff for a great service.
