Super happy

I'm sure I'm not alone when I say that finding weights during the pandemic has been difficult. I happened to stumble across the Zion Onyx set and was happy to see the price was pretty fair. Prices on a lot of olympic bumper and iron plates have been going way up due to them being so in demand for home gyms. I had never heard of Zion before but I am impressed how great these bumper plates are. Very high quality. What really made me happy is how quickly the Zion customer service responded to a question I had about my order. I had emailed them and literally received a response within 3 minutes.
Long story short - if you're looking for affordable, high quality bumper plates from a company with great customer service, your search should be over. I would happily order from Zion again

Zion Onyx 230LB Bumper Plate Set


Just amazing. They shipped literally 35 minutes after I ordered them and I received an email from them right away (from a real person). They arrived in 5 days and one of the plates was stuck in shipping. I emailed customer support and got a response within1 minute (not exaggerating). Well-built quality bumper plates, sharp looking, absolutely THE BEST customer service I have experienced anywhere. Don't hesitate, buy them now.
