Spartan Proposal!

The rings my fiancé and I got are amazing! They feel a bit tight at first but after a couple days fit perfect! I can’t even feel it when working out and everyone loves it. We choose the spartan ring because that’s where my fiancé proposed...AT THE FINISH LINE!

I ordered the wrong size and they sent one to me the next day. Told me no rush on returning the other. I had my ring within 3days of them sending out the original ring. Excellent service. Ring fits perfect!

Great Customer Service, Awesome Product

I would recommend Groove Rings to any and everyone. Customer service was second to none. These guys responded quickly and daily. I did not have to wait a week for replies. I had concerns with the size of my ring, they shipped a new one out that day no questions asked. I love this company. -Jonathan Brandenburg Dallas, Texas
