Weight Range
10–105 lbs per dumbbell (10 lbs to 100 lbs standard, 10.25 lbs to 105 lbs with micro kits)
Haven’t used them very much but from what i’ve seen they are very easy and quick to adjust. Goes up to 100lbs (for most that’s more than enough) so I got the 2.5lb and 1.25lb added weight as well. Very easy to install and the increment plates just click in. That said, I really dislike the weight plate increment rack attachment because the part seperating the plates is flimsy and doesn’t click in. This is no issue as it really doesn’t affect anything. They’re very easy to use and have very accurate weights. They feel nice in the hand (I have the knurled grip) and even the dials feel nice. So far very satisfied with the purchase and really hope it keeps working as well as it has.

I owned Powerblocks for over 20 years, and although they held up fine, they did noy feel like grabbing a specific dumbell weight off the rack at a local gym.
The MX100s I received are the most over engineered and realistic feeling dumbells I’ve ever used. Solid in shape, form, and fit.
My only gripe, and its a small one was the stand that purchased from MxFitnessSupply separately. Stand was about 80% under-engineered for such an amazing set of dumbells, and I used stainless 1/4” x 3/4” stainless steel hex self-tapping screws.
Once again, phenomenal dumbell set, but pleaee give the stand a fighting chance, charge more if necesaary and build it to the proper, complimentary specs.
