No probs Ben. I did buy the red 8mm Thermobore but with hot kept making my jet fall off the hose in the brush as I use the hexagon jets from Omnipole as they seem to make the water squirt out faster. Didn't think about keeping it for cold so chucked it in the garage. I use the yellow 8mm no probs with it m8. I think the longer the better as I can park up and reach around care homes with only two moves 👳✔
