"I have used these to isolate for basin taps with flexible connections and they work very well. Good quality and appear very well made. I prefer to use these rather than standard ball valve with slotted turn for ease of use."
"Good quality service valve and there are some shockers out there! I generally remove the handle whilst tightening the compression joints as it allows you to get an adjustable on the body without damaging the handle"
"I have used with frequent failure, water leaks from the slot , the screwdiver slotted service valves over the years. I find these handled ones reliable and of course more user friendly as no screwdriver required to operate. Individually packed ensures nuts and olives don`t get lost."
"Good product and I have used plenty. However, the operating handle is of poor quality and several of mine cracked even before I installed them and had to be replaced. The 22mm version is even worse for this problem."
"I have used many of these valves over the years. They used to represent excellent value for money, but more recently the quality has gone downhill big-style. They don't always switch off the supply as they are supposed to, and I have had many callbacks where I have had to change them because they don't work. The compression fittings are also now of very poor quality, and particularly unsuitable if using with plastic pipework.
Quite frankly you really do get what you pay for and it's not worth the hassle. I have stopped using them in favour of Conex 15mm Isolating Valves (Product Code: 78891) or 15mm Full Bore Levers (Product Code: 80413) dependant on the application.
Shame really - they used to be quite good, but now represent a poor investment. AVOID."
