Their only fault is they are not adjustable on-the-fly - you need to stop or slow down to change the settings. This is OK if you adjust them once or twice per workout, but are not practical in a rolling terrain.
If someone improved them by adding push-of-a-button adjustment, they would be the 'killer-app' in the rollerski world.
I adjust the speed reducers on the fly all the time, but not at high speeds! Anticipate the need 10meters ahead of time and it's fine.
