How much 50m garden horse pipe best quality?

Based on your question asking for the best quality 50m garden hose, I would recommend either the Wedgit - Premium Hose 19MM 3/4 50M Roll for R3442 or the Premium Garden Hose 12MM 1/2 20M 35BAR With Connector Starter Set by Wedgit for R829. Both Wedgit hoses are described as premium quality in the product names and reviews. The Wedgit 19mm hose is a full 50m length as you requested, while the 12mm hose is a bit shorter at 20m but is still highly rated and a bit cheaper. Let me know if you need any other details on these options or have additional questions!
