Rated 3 out of 5 by from Missing the connecting components. I unpacked the bag and found no connecting components when I took the packed goods back home. I needed to go to the toolstation again to exchange a new pack. Apart from spend time for the exchange, the product is satisfactory.

Rated 5 out of 5 by from Just the job. Brilliant piece of kit. You get a full flush by keeping the bungs in. Great price.

Rated 5 out of 5 by from Excellent! Bought the more expensive Thomas Dudley turbo at over four times the price as this one which had a terrible flush rate (was correctly set) replaced with this one and works perfectly. The black seal is actually of better quality than the Thomas Dudley just shows sometimes more expensive option isn’t the best..
