Definite buy

Great plates. High quality. Great looking. No odor issues. Definite recommend on this purchase, if you can get them.

Nice, love them

I received the weights I ordered today as well. Ordered the 170lb package and very pleased as they are a great addition to my other Olympic plates from Rogue. They were packaged well and look good. The smell is nothing more than the new rubber smell of any weights. Just like a new car smell. I would be worried if there was no smell because that would tell me they're old and not new. No smell guys to be worried about. Wears off like a new car smell or the smell of anything else new you buy. I like my home gym smelling like a gym, not "Bath & Body works" LOL!

Well made, comfortable weights

I bought these for my teenagers but i have been using them as well. The weights feel great...nicely coated with rubber which makes them easy and comfortable to move.

Very happy with these plate weights!

Great set for the money! The smell some other reviews mentioned isnt a problem and goes away after a wipe down and a couple of days. The best part is that the packaging was durable and double boxed and nothing was damaged during shipping! Very solid and well balanced plates. Very happy with the purchase.
