As you'd expect from a brand as established as Tunturi, the R25 is one of the best built rowing machines in its price range. The display is extremely clear and simple to use and the noise-free magnetic resistance has eight levels of tension. And while it looks a bit cheaper than some models, when folded it's only 94cm long x 53cm wide so can easily be bunged in a cupboard when you're hosting a posh dinner party.
