Tunturi C20 elliptical machine is pretty outdated. We recommend you to consider the Diamondback 1060ef elliptical trainer, instead.
Tunturi C20 Elliptical Machine Review
A lot of online reviewers agree that the Tunturi C20 is strong enough to stick out a frequent use by all family members (and friends too). It supports up to 9 users, allowing them to record the pulse and keeps them challenged in a safe zone. A usage by multiple users requires a superbly steady frame. Tunturi backed this frame with a 15-year warranty. The Tunturi C20 offers 8 levels of electronically controlled resistance, a 17-inch stride length which is a standard in the mid-price range of ellipticals, and a 31-pound flywheel. It is a fair value for its price. According to the most Tunturi C20 reviews, it is a superb elliptical machine in a low-middle price range.
