I personally do not like these bumper plates. They bounce erratically from side to side when dropped. The red 25kg plate grew a big circular crack around the edge. This crack developed only after a few months of lifting. You can see the crack in the picture below.
The positive remarks I will give these plates is that they are all uniform thickness and the 10kg green plates are very durable. Usually 10’s are the weakest of the bunch. However, for the price, you might as well get something much more formidable, like Eleiko or Rogue. For the budget conscious lifter, Bells of Steel has some good options.
