Great products, confusing compatibility PowerBlock is by far the best adjustable barbell out there. I've used 3 different sets over 10 years. The primary issue I have is compatibility for accessories. For example, there are various versions of the product line that are NOT clear what works with what, ie the EZ Curl Bar, what size of stand is needed, etc. Also the pull up bar attachment to the bench is unstable and I've had issues with it, not just stability but it makes using the bench troublesome requiring a lot of extra space or disassembly each time...

There's really nothing to say. The … There's really nothing to say. The dumbels arrived in a relatively timely manner (perfectly adequate given that I'd ordered them near Christmas. One arrived a full day earlier than the other which was, for a few minutes, very confusing and not a little worrisome.

My college has recently implemented… My college has recently implemented these for team lifting and they are very awkward and hard to deal with, while they do save space they make lifts which were once easy more difficult because of the strange block shape. Furthermore, the options for weight selections are very strange starting at 12.5 and adding weight on from there meaning we are left with options such as 67.5 and that makes selecting weight very difficult.

Great company, good products. We've made three purchases from PowerBlock and had no issues whatsoever with billing, shipping, or the condition of the products. The U series are our favorite adjustables. They aren't a perfect design, I would give the U70's 4/5 stars, but they seem to be the best adjustable dumbbells out there, and they are extremely high quality, they work exactly as advertised.

This company is terrible. Do not buy This company is terrible. My order came in damaged beyond use. Most of the plates are bent out of proportion. I have emailed them 7 times and did not get 1 response. If you order these dumbells and they come in damages, sorry you will not be getting help. $700 down the drain
