The safest and one of the quickest ways of drying your film. The cabinet has a built in heater that gently blows warm air over the negatives lessening the amount of time that particles in the atmosphere can attach to your valuable film. They can be dry in fifteen minutes.
If, like me, you only have a small darkroom then a cabinet may not be practical within the room itself. You could place it outside but the problem I have with that is it looks like a gym locker, making it a blot on the landscape wherever you put it! Oh! and they're not cheap! Make your own mind up!!
