Excellent Expansion Kit!
Great addition to the Power Blocks

So worth it for the expansion
An awesome upgrade to your powerblocks for adjustability. They are easy to use and very safe and secure.

A great weight set.
Perfect. I love these powerblock weights. They make storing up to 90 lbs so easy. The adjustment is easy and intuitive once you use them a few times. I don’t drop them or throw them, but they seem like they would hold up to a good amount of tossing around. The form and function are perfect for a home gym.

Problems fitting on the set?
If you think these are bent and not fitting on the set, take a breath, flip them around and they will slide on with ease ð

Outstanding just make sure which model youâre buying for
Everything I bought from power blocks has been immaculately packaged, and the equipment itself is just above par. Once you get past the unusual looking feel of the weights youâll fall in love with them just make certain which model you have is there are two different models of these dumbbells And I do not believe the white plates are interchangeable

70-90lb upgrade
*UPDATE* I REACHED OUT TO POWER BLOCK DIRECTLY AND THEY DID NOT HESITATE TO REPLACE THE FAULTY PARTS IMMEDIATELY. REALLY EXCELLENT CUSTOMER SERVICE!Purchased the largest upgrade, which was seventy to ninety pounds, and it is essentially unusable. Either the sixty pound block from the smaller upgrade or one of the 70-90lb weights was not made or finished correctly?And you cannot separate them. You can use the weights just fine up to fifty pounds and then you can use ninety pounds, but any weight in between you cannot separate them. Super disappointed I don’t have the box anymore and would love to have a replacement. As you can see, there are chips and parts of the finish missing also. These WERE my favorite part of my home gym. Will update my review if they reach out to correct the issue.

Save yourself some heartbreak: Buy a different product and buy it somewhere else
If I could give zero stars for the stage 3 expansion, I would.I have a Powerblock EXP set (5-50 lbs) expanded successfully with the stage 2 (50-70 lbs) expansion set. Because I have been using all 70 lbs recently in my workouts, I ordered the stage 3 set.Upon unboxing and unwrapping the stage 3 set, I find that both stage 3 expansion units are too narrow to accommodate my stage 2 enhanced Powerblock EXP dumbbells.I will attempt a return for refund.Amazon is terrible with product descriptions. I actually acquired the stage 2 EXP expansions before getting the basic EXP dumbbells set because that expansion set was represented on Amazon as fitting the Powerblock EXP _Pro_ dumbbellsâwhich they do not. (I bought the matching EXP dumbbells anyway because my spouse took up lifting and having two sets is thus worthwhile.)Powerblock has since discontinued this line of dumbbells in favor of a newer (and doubtless incompatible) set. Amazon canât keep expansion sets straight. Best to look for a different product and to look for it somewhere else.

These work great to up the weight capacity of the power block elites. I maxed out on the 50 pounds and needed another challenge.

Now really much to say it really adds the extra weight and build quality is nice

Ware ist gut verarbeitet.Man kann viele Ãbungen mit machen.Spart viel Platz allerdings sollte man sich den Ständer dazu kaufen.

Pleased with these, a simple but effective mechanism for adjusting the weight. The weight feels well held once the pin is fully inserted and I’ve not had any worries about part of it falling on me even with overhead exercises. I considered the other version of adjustable dumbbells for which the weight is adjusted by turning a dial at either end – but opted for these as it appears there is less to go wrong with this mechanism in the future. They’re not cheap so I’m hoping they will be durable.A few minor negatives – the pin can be fiddly to insert unless the plates are lined up properly. Also the label on the dumbbells states that the handle weighs 5 lbs. It felt a bit light for that – and at least on my kitchen scales it weighs exactly 4 lbs… All the other stated weights appear correct however, within about 500 grams.

Love these! Does exactly what it says on the tin. Great way to have a full set of DBs in a small, small space. Very quick and easy to change weights.For my home I might have bought the Sports 9.0 so I could go up in weight further – but these are perfect to leave at my dad’s as a mini-gym for when I am visiting. Very happy customer.
