So far so good, no issues.

Weight accuracy is pretty good. handle weight is almost 6lb.
plate weights dead on.
so my scale on both dumbbells is ~ 6, 11, 16, 21, 26 etc.

They feel great. Compared to the rubber hexagon weights the handles are much better. The adjustability makes them extremely convenient and practical.

Moving from the hex style individual dumbbells to these 50 pound adjustable ones. They are well designed and work as expected. The weight is well balanced and have nice knurled, thicker handles than those tapered hex ones. I feel I have better overall control with these new ones!

Its the best dumbles i can ever purchase and iam glad that i purchased it from LOGANFIT they have a very reasonable price.

Quick delivery & quick responses. Great product as well!
