It has solid case helps to protect the plates and prevent any from being misplaced.
- USA Home Gym
Overall a very solid set of dumbbells that do not include any plastic parts, unlike some of the expensive adjustable dumbbells, the Caps can be dropped from a height if you like to train to failure, no need to worry about breaking expensive adjustment systems with plastic mechanics inside. You can throw these around if you wish, they are almost unbreakable.
- Jay's Home Gym
Durable cast iron plate has a semi-gloss finish makes it rust and maintenance-free.

Spin On Collars: this type of collar is my favorite. My barbells have them too. Sure, a turn on the collar is not as trendy nor cutting-edge as some of the locking systems found on other adjustable dumbbells are; however, the spinons feel so stable and safe to me!
- Form Me Fit
What I like about the Cap Barbell 40-Pound Dumbbell Set is it comes with removable plates. These plates are cast iron and extremely durable.
- Optimum Fitness
Attractive – These are made keeping the look in mind for sure. The bar and plates come with a beautiful baked black enamel finish. This makes the dumbbells stand out.

Depending on the speed of your strength gains, you may find you grow out of the 40 lb limit quite quickly. (Additional weight plates can be purchased to upgrade the weight)
- USA Home Gym
Only 40lb of weight in the set.
- Jay's Home Gym
Some people will find the grip a bit too rough.

Handle Ends: they can hurt you if you rest the pointy end of the handles on your thigh while they are loaded up. You may accidentally do this when getting ready to do some heavy dumbbell bench presses.
- Form Me Fit
Odor – These can be a bit smelly to use sometimes. But that’s the case with all cast iron products in fitness. This is a problem only if you are ultra sensitive about odors.
- Tech Impose

Some users may prefer to adjust weights in smaller increments.
- Diets In Review
There are no rubber washers on either end of the dumbbell bar. As a result of this, the weights sometimes keep clanging against each other.
