Reliance manifold

[Super_Paulie]

hi guys, does anyone have any experience with these? Reliance manifold.

Zero screwfix reviews suggests they are either very new or very average... the price point is a lot more friendly when compared to the Speedfit or Hep20 manifold when you need a shed load of them. 

Just weighing up whether it is better to build my own in copper-isolation valves or go down the pre-built route.
