Set the dumbbell in its docking base, twist the handle, and the 8552 G4 moves anywhere from 8.5 to 52 lb in micro-increments. The dial reads in both pounds and kilograms, 4 to 23.5 kg. One pair does the work of 28 fixed dumbbells, which is the argument for putting it in a room where a full rack was never going to fit.
Length changes with load. Select a lighter weight and the dumbbell is physically shorter, so the plate stack always matches what you are lifting. Plates are cast iron under an electroplated stainless finish, the handle is 34mm aluminum, and the base occupies 370 x 215mm of floor. Trulap warranties the set for 3 years from date of receipt.
