What's your take on adjustable dumbbells?
I recently bought that Reebok Adjustable-a-Weight dumbbell on sport.woot for $30 and had to send it back because the base arrived shattered (thanks, FedEx). Needless to say, I'm still in the market.
What's you opinion of adjustable-weight dumbbells? Are they worth the added expense? Are they safe? If yes, then which brand is the best value?
