Sealey TSTPGD

Take price out of the equation, and this Sealey unit would have cleaned up. It was superb in the accuracy tests and comfortable to use. Features include a bright LED torch, backlit display and non-slip grip. A belt clip and decent instructions also won points, and it fitted neatly to the valve. But it's not worth double the cost of rivals.
