The details.
Mr Reliable is a high-polish tungsten carbide wedding ring for men who want a classic mirror-bright band in the width that suits them. It is offered from 4mm to 8mm wide, so it works for slim fingers and broad hands alike, and the hard surface keeps its polish well.
Why people choose it
The range of widths means the same design can suit either partner. Tungsten carbide resists the scratches that mark softer metals, and the weight gives it a solid feel. The comfort-fit interior makes it easier to get on and off.
Details
- Material: tungsten carbide
- Finish: high polish
- Widths: 4mm, 5mm, 6mm, 7mm or 8mm
- Fit: comfort-fit interior
- Sizing: 23 sizes, listed in US sizes first
- Tungsten cannot be resized, so size carefully
- Model: Mr Reliable (SKU FTR-021)
Who it suits
A straightforward choice for a wedding band, an anniversary or a gift for someone who prefers timeless style over bold design. Choose a slimmer width for a lighter, traditional feel, or go to 8mm for a band with more presence on a larger hand.
Delivery
Every order is sent with tracking. In-stock orders are usually dispatched within 1–2 business days (Monday to Friday). Delivery time depends on your country. Prices are in US dollars.

Style and strength, looks great and can stand up to everyday life without getting dinged and scratched. I had been wearing a similar black tungsten ring and simply wanted a change. My old ring has held up over time, don't need to be precious and take it off to do outdoor work, gardening and construction.

Dropped my original Tungsten Wedding Ring and it broke in two, it was so easy to order a new one and working out the size with the free ring sizer was easy. Ring arrived fast and was a perfect fit. Fingers crossed this ring last me another 20 years.

We purchased a tungsten ring for my partners wedding ring. It came excellently packaged and super quickly. We're not married yet but he is very eager to wear it =)

Exactly what I ordered and arrived in good time

Brought for my husband as a marriage renewal ring. Beautiful ring, heavyweight but ok for men. Needed a ring to last as he is a truck driver I didn't want it scratched up.

Tungsten - highly durable, tough and an awesome gun metal colour. Another plus is it's a lot cheaper than platinum (the other metal I was considering). This is a great ring for those who want something practical and who don't care what others think about the metal of the ring.
Mens Rings Online are a great seller with super quick delivery and a hassle free returns policy which I had to use when the ring was slightly big. One swap later which took less than a week and I have the ring I need. The only sad thing is the ring is 20% off a week after I bought it, but that's life!

Awesome ring, hubby is so happy. . he works on estate roads and not once has he got it scratched. . highly recommend to hands on workers. .

Ring is as beautiful as it appears, I am happy with it, as is the recipient. The packaging however left a lot to be desired. The ring had a tag for some masquerade rubbish on it. .. . shouldn't you get your branding right? The box had clearly been used before, the part where the ring box sits was ripped apart, and the interior was notably dusty (display box?), and this was a gift. I'm glad I peeked inside, before I gave it to him! I probably will not purchase again. It's the little things, ya know.

Buying anything online that you're going to wear risks. For me, it's not the money - it's about the time time lost, and the stress and confusion that comes with trying to get the right size or sending it back and getting it delivered to the right address. .. you know the drill.
This whole process was seamless. My fiance ordered the ring. It arrived in a day or two. It didn't fit properly. I took the ring sizing zip, tried it on, found out what I needed. I sent an email for my replacement code, placed another order, sent the ring back, and, again, in about two days, got my new ring.
It fits like a dream. It looks great. I barely had to think and it was easy on the wallet.
If buying jewelry isn't your thing, this is the best place to go. Might be spoiling myself to another piece soon.

I had to exchange my first ring for a different size. The returns process was quick and pain-free and the sizing tool they included with the first ring helped me order a ring that fit perfectly. Very happy with the overall process and with the quality of the product.

My fiancè loves this ring and can't wait to wear it when we are married. We purchased the incorrect size and it was so simple to return and re order. Thanks for making it a smooth process.
2018-05-28
Exceptional quality band however I am scoring 4 stars due to being sent the wrong size and I had to wait a few months for the right size to come back in stock. Then I had to remind them to send my exchange band before it would go out of stock again. However I appreciate the prompt communication from the seller and being able to exchange for the right size band. The price is also fantastic value for money and quality.
2018-04-26
Absolutely stunning ring, fit perfect. He loves it!!
2018-04-09
Great service was able to change my ring size and design with no trouble
2018-03-15
If you'd like a ring on your finger that you can feel, this is for you. It was fairly heavy, and even though it was too heavy for me and I returned the ring, it was great quality and felt like it would like a lifetime. I have small hands and just didn't suit me. If you have large hands this would be perfect.
2018-03-04
Initially swapped the first ring chosen as it was a little on the thick side. Really easy to replace with this ring. Great service very happy with the quality
2018-02-16
I bought my husband a replacement wedding ring as he lost his at the beach. The ring is fabulous, a lot cheaper than buying in the store and it fit perfectly. Thank you!
2018-01-06
High shine finish -- I can see my face reflected in the surface. The ring feels heavy and expensive in my hand. My husband had this ring previously but lost weight and the ring slipped off while he was swimming. He liked it so much that we re-purchased the same design in a small size. The shape is classic but the material, colour and finish make it look modern. Highly recommended
2017-11-12
Clean simple design, love it and very fast postage so it came in time

I would like to thank you for great customer service and a great ring that my fiancee loves! He rates the ring 5/5.
Firstly, you have a great selection of rings and metals, and had exactly what my fiancee was looking for. The first ring we ordered was unfortunately slightly too big, so I sent a message on your website and was responded to almost straight away by Charina. I sent the ring back the following day and ordered a smaller size ring. Both rings arrived within a few days of ordering which was great, and the second ring fits perfectly. The ring sizer that you sent is great and very useful for us when we needed a smaller size.
We had a very positive experience with your service, and would definitely recommend your website to others.
2016-04-12
I just wanted to thank you for your great service, yesterday I received my replacement ring (the original one I ordered was too big), and it is perfect. Very fast shipping which is great. Thank you again for a great service!

We recently purchased my fiancé’s wedding ring from Mens Rings Online and the service was amazing. The ring is exact try like the picture - in fact we were both shocked as it exceeded our expectations. We had sized his ring finger incorrectly so had to exchange and the process of doing so was quick and efficient and the communication was outstanding. I would highly recommend this company to anyone and will most definitely be using them again.
Thanks again, an absolute pleasure to deal with.
2014-12-29
More than happy to give you guys 5 out of 5. Fantastic customer service. Great refund policy as I ordered three rings and sent two back to make sure I got the right size. Great pricing and the product was spot on. Couldn't recommend you highly enough. Shame you only ever need to buy one in your life otherwise I would be back for sure. Thanks again.
