Rated 5 out of 5 by Exactly what I needed This expansion kit has turned my PowerBlock workouts up a notch, and they work just as smoothly as expected from this great product. I'm extremely pleased with this product, and I feel that this has been one of my best workout item purchases ever. March 30, 2014
Rated 5 out of 5 by PowerBlock 20 lb Expansion Kit Works well with my 50 Plus Dumbbell Set. Very satisfied. March 8, 2014
Rated 4 out of 5 by Good product I have been happy with my expansion pack. The weight selectors do not go as smoothly into the expansion pack as they do into the standard dumbbell. Other than that small glitch I am happy with them. February 5, 2014
Rated 5 out of 5 by Nice Addition Fits my powerblock classic 50 plus a little expensive but works great and gives me a good challenging workout November 8, 2013
Rated 5 out of 5 by Great deal I got these for $80. Great find at that price. I would recommend them to anybody looking for dumbbells. May 7, 2013
Rated 5 out of 5 by Make Sure it fits I ordered this product and when it arrived it didn't sit flush with the weight set, I think the package was probably dropped in transit. Anyways I reordered the weights and they fit perfect the second time around. Overall very pleased with having dumbbells that now go from 5-70 pounds. I know its a little pricey at $150 but the $299 set plus $150 is still a value at $449. The elite 70 on the powerblock site is $428 plus shipping, so its about a $21 difference. May 2, 2013
