Had a Hozelock double-tap adaptor which the son managed to break, and so bought this as a replacement, hoping it would be compatible with the Hozelock connectors on the pipes. It is, and is a solid piece of brass with tough plastic taps. Much better than the dial on the old adaptor, which never felt that solid and the dial to split the water was a vague awkward movement. No sign of leakage, fitted very easily, I'd rate it as a quality well-machined product. Was supplied as a twin-tap with two adaptors (the picture shows them fitted, you have to attach them yourself, not a problem).
