The ZR10 is a little bit more expensive than the ZR9 and the ZR 8; however, it has various additional features to justify the added cost. These consist of a much faster maximum speed (18km/h contrasted to 16km/h), a wider variety of incline options, and extra integrated programmes. Considering there isn’t a massive distinction in price, we assume the Reebok ZR10 offers better worth for money, although both designs are good low/mid-range treadmills.
