My fiancé is thrilled with my purchase, and my grown daughter said it’s the most badass wedding ring she’s seen. Ship time and communication was awesome-size was spot-on, too!

I purchased a ring for my partner - it arrived quickly, beautifully presented, and excellent quality for the price! Unfortunately, it was a little large - however the seemless returns process (including the nifty little sizing band included with the order) meant that it wasn't a big problem to return for the correct size, and also a design he really loved. Thanks MOR. . We'll be back when it's time for a wedding band :)

The ring arrived yesterday, thank you. It is a beautiful ring and I think my partner is going to love it! So beautifully packaged too. I would give you a 5 as you answered me in quick time on my enquiries and made sure the ring arrived in good time. Your attention to detail is second to none!

Hi, I would give it a 5 star rating. Delivery was super speedy and the ring made it in time for Christmas! It fit perfectly (luckily, as I guessed size). The ring is beautiful, even better in person and I'm so happy!
Thanks,

Great service and very prompt replies to questions and queries. Ring was delivered very quickly but slightly too tight. Arranged larger replacement with turn around time better than advertised. Very happy with the final result of the actual product and very happy with the service.

Ordered ring arrived after two days, looks fantastic and fits perfectly. Highly recommend buying from mensringsonline. Looking for next purchase already.
2016-05-13
Absolutely gorgeous ring. Better than the picture. My fiance & I chose it as his wedding ring and are stoked that we did. Were originally going to purchase a ring elsewhere for about 8 times the price til we found this site. .
Ordered one day and literally received the next. . Absolutely gobsmacked considering we live in different states. Thank you so much for such an easy transaction.
I will definitely shop here again and spread the word!!

Love this ring!
Great price!
I used PayPal, initially there was a problem on the website side, but they sent me a PayPal invoice and, I paid it, and the ring and box arrived successfully!
Love it! Everyone that sees it loves it!

I purchased this ring for my partners birthday and he adored it! Everything about the ring, the weight, the colour, size, everything!
In fact I fell in love with the ring myself too bad it’d be weird if I bought myself one!
I would give the product a 4.5 out of 5 and only because it’s slightly too big, if you could have examples for sizes (maybe you do but I couldn’t find it) or something similar to that that would be great because obviously it is very different to buying a ring from a Jewellery store.
The customer service I received was good, it wasn’t hard to navigate around the website nor did I find it hard to find exactly the kind of thing I was looking for.
I think your website needs to be advertised more because they are fantastic rings for fantastic prices!
Overall I don’t think you have anything to worry about, it was more than I could ask for.
