Review: A steal for the price - 30kg of good weights, and a good set of dumbells and a serviceable barbell all for £100 is a bargain, especially when good 10kg plates are costing around £50-70, this is a great place to grab some dumbells with some nice quality metal plates. The set obviously doesn't come with a massive amount of weight, but it's easy enough to supplement it by buying more plates as you need.
Review: Good quality for good price - Lovely set of weights with nice option with bar extender. Was a little concerned as took longer to deliver than ‘next day’ but is 30kg so quite heavy. Better finish than York cast iron plates. You can buy more expensive sets but iron is very robust and if dropped doesn’t deform.

### ⭐⭐⭐⭐ Okay
*by H***Y on 30 July 2025*

These are as advertised. I got the 30kg set. The bar weight is included in the overall weight. So the plates add up to 27kg. The plates are well manufactured. They are a bit smooth and slipp about easily. The other ones I already own are a matt finish that is not shiny or slippy. I find them better than these weights for that reason. The shape and size are different to the plates I already own which I did not expect. I thought all cast iron 1" plates Wouldham some kind of universal diameter and thickness. It seems not. These are larger in diameter and thinner. Obviously this changes nothing in terms of weight. I can still use the old weights and These new ones together, however I will probably match each dumbbell and each side of the dumbbell for symmetry and in case of weight distribution differences. The box came quite damaged and completely open on one end. No parts were missing though so I am still happy with purchase. I went on to find a 20kg set that was cheaper to the point that I coukd have bought 2 of thse sets to get 40kg with 4 bars for the same rice as I got this 30kg set that has only 2 bars and a mid joint I will probably never use. I didn't want the hassle of sending this set back when there is nothing wrong with it for the better price to weights ratio. I would recommend this set but would also recommend researching other sets and working out how to get the best quantity and quality for your bucks.
