I think they are a waste of money

better off getting a separate powermeter and a decent set of rollers for riding indoors. That way you can still get power readings when you go outdoors as well.

Powertap have recently released the C1 chainrings which cost about a quarter of the price of a wattbike and are much more versatile.
