POWERBLOCKElite EXP 70-90 lb. Dumbbell Kit, Stage 3 Expansion Kit, Only Compatible After Stage 2 Adjustable Dumbbell Purchase, Durable Steel, Innovative Workout Equipment Black

Great addition to the Power Blocks

An awesome upgrade to your powerblocks for adjustability. They are easy to use and very safe and secure.

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.

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 👌

no issues works great

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 you’ll 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

*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.

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_ dumbbells—which 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 can’t keep expansion sets straight. Best to look for a different product and to look for it somewhere else.
