Horrible products. Purchased a bunch at the same. Started noticing green finger. Material of ring fading. Emailed CS. The reply we received was sorry over 1 year, buy a different one and here's a coupon code.
Actual deterioration because around month 6. And never wear them all day straight.
Terrible quality. Terrible cs.
Final thought. If you want a men's ring to last say 4-6 months, minimal wear - invest in this.
