Great beginner set
Bought these to replace a set weight pair and I really love these. I can adjust as necessary for my comfort and they're easy to alter. They are great quality and the grip bar is very comfortable.

Pair of Cast Iron Dumbells 20KG Back
Well made and optically looks good. The locking mechanism works well and does not loosen. Compact design and stores away neatly.

Great!
As a beginner I’m finding the weights a great starting point. Really easy to use. You just have to make sure you keep the screws tightened. I maybe should get some gloves because the metal bar is making my hands a bit dry

Good weights
Good set of weights for the price, although the image is misleading as the bar to put them on is not that long as shown in the picture.
