Hefty Bulldog weighs the most, at 12.5kg, and is the roomiest safe. It has a monster 10mm thick, 1.8-metre long steel cable. Easily held two 17-inch laptops, plus our test gear, with space to spare. Radial pin lock secured the lid well, and the cable has its own built-in lock. But at this price, it’s clearly designed for professional use.
