Info on Adjustable Dumbells

[Pekkerwood]

Any feedback on adjustable dumbells? Before the flames I am not using them for my regular super-human workouts. I want to use them during my morning cardio on the recumbant back to help pass time by doing some high rep curls, lateral raises etc.

I don't have a true exercise room, just a bike up in my media room an prefer not to have a dumbell rack if possible.
