Do under desk pedal machines help??

Basically the title!

Does anyone own one of these under desk pedal machines? Does it help? Theoretically sounds asweome, I spend long hours at my desk (like any other corporate slave) and if I constantly cycle with this it'd be very beneficial but getting a fitness tracker that reminds me every hour to get up and move was also a good move in theory that didn't quite translate that well into practice

Would appreciate any opinions!
