I needed a replacement heater for my hot tub. Found one on another site and ordered. When it hadn't arrived I contacted them only to discover that they wanted an extra 12 to ship on top of the 7 already charged. So I looked around and found hot tub diy. The service couldn't have been better. The owner helped me choose the correct model as there are a few similar models. Not only was the heater cheaper but I was only charged 6 to send to the Highlands. The heater itself was actually over 100 cheaper than some sites. I will not even look anywhere else for my parts in future. Great price, great service. Thank you very much the heater is fitted and working perfectly.
