(More customer reviews)I agree that these are the best adjustable dumbbells on the market.However, I would add a few caveats.For starters, it is important to have the PowerBlocks on a level surface and make sure you insert the pin straight across rather than at an angle.If you don't, it is possible that a plate could fall and hit you even with the elastic backup mechanism.It is also very important to put the pin assembly together right side up.If you don't, the magnets that hold this assembly in place don't engage.
On exercises like OVERHEAD triceps extensions, the points above are particularly important.While I think this product is great, it does limit range of motion in some exercises such as upright rows.The dumbbell is rather long and this could be a problem depending upon your frame.However, I wouldn't worry about the square design.I find using these dumbbells to be quite comfortable and the padded grips certainly help.
While this product is quite expensive, it's also the best out there that I know of and I shopped around carefully.It also seems to be the safest and is certainly more convenient, takes up less room and even costs less than a set of full dumbbells that can cover the same weight ranges.
If money is an issue for you, you may want to consider getting the model of dumbbells one tier down from these that adjust in 5 lb. increments and then purchasing adjustable wrist weights in 0.5 increments.This will give you about the same effect for less cost.

Product Description:
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 personal trainer set is a hybrid system that employs the weight stack from PowerBlock's Personal Set and the handles of the Elite Set. As a result, users can achieve every 2.5-pound jump within the weight range of 2.5 to 50 pounds per dumbbell, in effect doing the job of 40 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 personal trainer set is not expandable and is compatible with the Elite/Pro weight stand. It also carries a limited 10-year warranty.
