I take off a star because spend 7 kg (1.2 + 1.8 + 1.1 + 1.1) 7.8 kg requires to replace the two discs of 1.1 kg by those 1.5kg but in this configuration the disk of 1.5 kg (which is not the same central diameter than 1.1 kg) moving on the stem. It would have sufficed to provide a small brace of 100 g to simply stall the drive 1.5 kg so that it does not move in this configuration and switch the dumbbell to 8 Kg. It's a shame to have neglected this detail, while the design and quality of the product look very good. Most handymen will make the missing spacer in a piece of wood.
