I ordered this as a repacement for a low pressure shower which was incompatible with my new combi - boiler. The original manufacturer wanted around £180 for a high pressure valve assembly... This unit cost about one fifth of this, is so easy to control and their are no leaks!
I bought this to use with a Yamaha keyboard which I have just bought. The chair is easy to assemble and the height adjustment is great - now I can play with the correct posture. Pity there aren't any stools with back support - maybe I will grow out of this as I learn to play!
