PowerBlock Pro 100 Adjustable Dumbbell – Great Quality, Just Misunderstood!

Competition bagSeptember 24, 2024

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.

Best adjustment dumbbells!

WesMay 19, 2025

PowerBlocks have been around for decades. These are the newest editions, and they are for sure high quality. They are the best value for the money as it saves a ton of space, and from having to buy regular dumbbells. They are quick and easy to adjust the weights and they can be fitted in a small space?

Misleading title and description but still great

Zachary JamesJuly 22, 2025

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.

Compact, stable and convenient but expensive

CustomerApril 22, 2025

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. Read more

What you expect.

80's baby maleAugust 1, 2024

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. Read more

Great for home gym!

CustomerOctober 6, 2025

These are an excellent home gym buy! The stackable aspect makes them space conscious. They are easy to use and understand. I don’t love the square aspect, they can be slightly inconvenient for certain lifts but overall for a home gym they are worth it. Read more
