Great bumper plates!

These plates are solid and at a great price. They were packaged nicely when they arrvied. Other reviews have mentioned a smell--but I never noticed anything. I have been using them in my home gym for a couple months and their quality is great. Their customer service is outstanding. I will definitely purchase from them again.

Love these plates

Wasn't sure I'd like these plates when I first ordered them, but so glad I did. Easy to handle and still feel firm enough to handle any drops. LOOK AMAZING! Great purchase!

Top quality at a good price

I have a home gym and all my plates were of a particular brand. I recently purchased a leg machine and needed new plates. These were every bit as good and about half the price. Highly recommend.
