"The hand tightened tap connector does work very well - ideal for all those taps where access for a spanner is at best difficult. The greatest advantage though arises when connecting to the plastic spigot found on many WC cistern fill valves. It can be near impossible to get conventional flexible hose tap connectors to seal properly - these however just work, no trouble at all! Will bend like the metal braided hoses although you push a bit harder. And they look good."
