"Since marrying my wife I have wanted a matching ring to her wedding band (she also has a thinner 3mm titanium ring for her wedding band) and after 3 years she bought me this one to match hers after loosing weight in my hands! Thanks!!"
"You won't be able to return a titanium ring if it doesn't fit optimally, so you have to order the perfect size, on your first attempt. The only way to achieve that is to: n1) Buy a set of US sized ring bands (aluminium) from eBay ~US$10. . . . . . n2) Buy a low cost digital measurement calipers ~US$18. . . . .n3) Try the bands and measure the internal diameter, to the nearest tenth of a millimeter, for the band which fits best - this confirms the size bands didn't fail quality control. . . .n4) Check which US size matches your millimeters at https://www. brilliance. com/ring-size-conversion-chart. . . .n5) Order the ring based on the US ring size - which is not in millimeters.n6) When you get your ring, measure it using the calipers to confirm it's exactly the size you ordered.n ###nI did this, and everything worked like a swiss watch. The ring I received precisely matches the size I ordered, and it fits my finger perfectly.n ###nIf you're not prepared to do all this then I suggest buying an Inner Circle where you can get your jeweller to ream out the wooden centre if you need an expansion, or replace the wooden centre with a thicker one if you need a reduction."
"Had a great and simple experience being able to return and get a new ring due to my own sizing error. The sizing tool included was a great help. Shipping is fast leaving little wait time. All of this on top of the ring being of great quality."
"We hesitated with our purchase but shouldn't have. The process was easy and we received the perfect ring in the perfect size without issue. We chose to visit a local jeweller and have a ring size measured and purchased the $1.99 ring sizer from Mens Rings Online first because we were ordering a custom ring. Very happy with their service and product received."
"I have never seen or recieved such an amazing service. We did order the wrong size and the return was quick and no fuss. The quality of the ring is outstanding and my husband loves it! Which is huge as he doesn't like rings. The communication from customer service was fantastic and helpful, all someone could ask for. Anyone with second thoughtsn. . . DON'T. . . . Just order the ring you like as you will be looked after and receive your ring in the most amazing beautiful packaging within days as we did and we live on the opposite side of Australia from the company.nnThank you Mens Rings Online for the best service I have ever recieved in retail."
"Initially I ordered a Tungsten and Koa Wood Mens Ring which arrived very promptly. A stunning ring, however it did not fit as I was unsure of sizing. I used the ring sizer that accompanied the ring and was able to exchange for a custom Titanium ring. The process was very easy and MRO kept me up to date with regular contact. Very happy with my end product."
"Very happy with this ring. Simple and elegant. Also experienced incredibly good customer service."
