From The Manufacturer

The Sport 24 has weight range from 3-24 lbs per hand in 3 lb increments. Sport 24 replaces 8 pairs of dumbbells or 216 lbs of free weights in the space of just 1 pair. Increments: 3, 6, 9, 12, 15, 18, 21, 24 lbs per hand. Built to last with a 15 year home use warranty, the compact patented design is engineered for maximum balance and control. Realize your strength training goals while keeping your workout area neat and organized. Ships in 2 boxes. The only dumbbell system that can expand to meet your strength needs, PowerBlock dumbbells are the most versatile and effective exercise tool ever developed for strength training. PowerBlocks work intuitively. Rather than requiring you to buy a room full of dumbbells, PowerBlocks act just like a weight stack at the gym, with a weight handle that fits inside the first weight, which fits inside the second, which fits inside the third, etc. When you want to change weights, you simply move the weight selector pin into the appropriate slot and you’re set. As you lift the core, all the weights above the selector pin are lifted at the same time, turning your 3-pound dumbbell into a 6-pound dumbbell, or your 6-pound dumbbell into a 12-pound dumbbell. Not only is the system remarkably easy to use, but it’s also cost- and space-efficient, as a single pair of dumbbells can do the work of dozens. This pair of SportBlock 24×3 dumbbells, for instance, adjusts from 3 to 24 pounds in 3-pound increments (3, 6, 9, 12, 15, 18, 21, and 24 pounds), in effect doing the job of 16 individual weights. Even better, the weights are more compact and balanced than traditional dumbbells, with a padded handle that protects people with weak wrists. Best of all, the free weights are terrific whether you’re trying to build muscle mass, firm and tone your physique, or get rid of unwanted body fat. The SportBlock set offers a maximum weight of 24 pounds per hand and carries a limited 10-year warranty.

The quality of this item is just superb. Other adjustable dumbbells are made of plastic composite or have plastic parts. Power Block Sports Block 2.4 Adjustable Dumbbells is simply metal. You do not have to cuddle it.
Another great feature of these dumbbells is their comfort nature. The padded handles are fantastic as the compactness keeps them from rotating while you lift them. When weight is compact, it makes it even safer.

Mastering the weight selection process --which involves sticking the weight pin incorrectly --can be challenging.

They are not comfortable over the shoulders.
