Hi Shaun, thank you for your review. The general idea is if you purchase a hose reel for out the back, you get this free pack to fit your hose around the front of the garden. Therefore, converting everything over to Hoselink in one go! Of course, if you are already kitted out with Hoselink around your yard then you can keep these as spares or they would be a great gift for someone. Kind regards, The Hoselink Team
