Satisfied
I weighed each plate when they arrived and they were all correct within what seems to be the margin of error on my bathroom scale.
They arrived quite oily, which caused a minor annoyance, but I think this is just how they come from the factory (I'd never used brand new bumper plates before and, based on some reading online, it looks like this isn't unusual). I recommend cleaning them right after receiving them with some wipes or soap and water to keep your hands from getting too slick when handling the weights.
The plates have no odour to them at all (which I know is a problem with some bumper plates) and perform as expected.
I would say these are quite good value and I would recommend them to pretty much anyone looking for bumper plates.
