The Stamina 25 lb. Versa-Bell II Adjustable Dumbbell is a 5 to 25 pound innovative dumbbell that replaces 9 individual dumbbells, but is the size of one so you save space-and money-without sacrificing quality. Increase or decrease the dumbbell's weight in a matter of seconds to transition smoothly from one rotation to the next.
Owner Reviews, Ratings, Comments and Criticism
the lock-on mechanism is a little wobbly, but if your plan is to simply start at one weight and then gradually graduate to a heavier weight month by month, these are great.
But if you intend to make daily changes to the weight (for different exercises, for example), you might find yourself getting slightly annoyed at having to slightly wiggle & jiggle the weights and knobs around to get them to fit onto the bar.
also, the lightwieght plastic tray tends to get wedged to the weights, so don't in a million years imagine yourself "plugging in" the dumbell, flicking a switch, and then picking it up (with less weight or more weight on it) in one smooth quick fashion... You need two hands and at least 10~15 seconds to get anything changed on these.
