  • PowerBlock Pro 100 Adjustable Dumbbell – Great Quality, Just Misunderstood!
I recently ordered the PowerBlock Pro 100 Adjustable Dumbbell and while I was impressed with the quality, there was a slight misunderstanding regarding what I received. What I Liked: Solid Build: The dumbbell feels well-constructed and sturdy, which is important for effective workouts. The adjustable feature is a great space saver and allows for versatile weight options. Easy to Use: The adjustment mechanism is straightforward and quick, making it simple to switch between weights during my workouts. What I Didn’t Expect: Single Dumbbell: I wasn't aware that I was only receiving one dumbbell when I placed the order. This led to some confusion and ultimately resulted in my decision to return it, as I was looking for a pair. Overall Impressions: The PowerBlock Pro 100 Adjustable Dumbbell is a great product for anyone looking for high-quality adjustable weights, but be sure to double-check the details about the quantity when ordering. ... show more

  • Perfect for Home Gym - Best Adjustable Free Weights
Extremely useful, the high weight options will let us grow for a long time. Love that they don’t roll around and they are super easy to change weights. We were first concerned that our wrists would hit the sides, but haven’t run into any issues.

  • Compact, stable and convenient but expensive
These things are awesome and compact compared to a full set of dumbbells 10LB-100lbs. The grip are significantly larger then average so consider that when buying. My lady can’t use them because the grub is too big but I love them. They seem secure when using but they do make a little noise when moving. I’m just hoping that the locking mechanism holds up too the repetitive adjustments I’ll be doing. ... show more

  • Every dumbell weight you'll need
Perfect for limited space areas. Very easy to adjust. Feels sturdy and safe.

  • What you expect.
They are what you expect. They are long with all the weight attached. The top of it when you measure is a little bit over 19 inches the bottom is actually a little bit smaller around 18 1/2 inches. The weight Is accurate well as accurate as a bathroom scale. Easy and fast to change the weight via the sliding fork. Changing the smaller weights are a little bit more complicated but easy enough. The rubber grips are the perfect size for my hand size. Have not had them that long. I will come back in about a year to tell you about the longevity and quality. ... show more

  • Misleading title and description but still great
Looks like a great product just not what I expected based on the title and description. The title says 5-100, the dumbbell starts at 10. The description says you can go up by 2.5 or 5lb increments but you can only go up by 10s. Im building a home gym for private training and this is fine for me but some of my clients really appreciate a 5lb or even 2.5lb increment when going up. When changing the weights, the dumbell and add-ons need to be completely flush with each other or it won't go in. The adjuster handle seems like it will break first and its kinda flimsy. The handle for me is great. Its thicker than normal handles which is a huge plus and the grip on it is very nice as well. Overall, if I knew this was 10-100lbs I'd still have bought it and given it a 5 star rating, so im not returning it but now I need to buy another of the same thing AND a set that does start at 5 and go up by small increments so im giving it a 3. ... show more
