Hello There, I started to train at home again after about half a year. In addition to my dumbbells I wanted to buy another EZ-curl bar and additional weights. I just wanted to have cast iron weight plates, there were not so many choices. I was afraid that the dumbbells are significantly larger by the intervention as weight plates without intervention, but this is not so. Through the interventions can be considerably more different exercises to perform and so I prefer even the most weight plates the dumbbells against. The quality is as it should be. The paint may peel off, but this is normal and my 30-year old cast iron weight plates also nurnoch sporadic paint. But does not interfere with and this happens just when the discs rubbing / beating. Conclusion: The discs are cheap and available for other discs in no way inferior. Agrees with the diameter and the intervention makes me happy. Who wants to have any intervention should for other discs seek think that does not make a big difference. Casting is cast. But I'm super happy with my 2x10kg slices and my 4x5kg discs. Hello There,
