This is better than the ones you find in stores for a few bucks.It looks like a wedding ring, but fits my husbands fingers so he’s able to do anything, or so his finger doesn’t swell in his sleep.I ordered a 10, and immediately after thought I should change it to an 11. I asked the company to replace the sizing before shipping. They let me keep the size 10 as a gift and and shipped both rings out at the same time.The10 fits perfect, and so does the 11.My husband likes the quality- and it doesn’t have that weird flea collar texture like some silicone rings have.Definitely recommend this ring and the customer service with the local seller is amazing.

I liked the ring I originally received from Knot Theory but it was a bit snug (when you order go UP 1 size from your normal and you should be fine) however the band started to separate. I returned it then was surprised to get an email from Jay in their customer service department wanting to know what the problem was, and offering to replace a ring I had already returned to Amazon as they wanted me to be happy. He told me they had a problem with a small batch of rings that had the separation problem, and helped me size it properly (see knotheory.com for the guide), and quickly shipped a new one. Can see and feel a difference in the quality from the bad batch, fit is much better, and it is very comfortable as well as safer if you work with your hands (I'm a railroad employee). I would recommend this ring not just for the product, but also for the outstanding service and how the company stands behind their product!

I am semi-retired and working for a rental car agency now, processing and delivering cars. In other words, I get in and out of hundreds of cars and a car wash all day. The last thing I wanted was for my "real" wedding band, which is an 11 and usually a tiny bit loose, to get caught on something, fall down a grating, or be lost in a car. I ordered a 10.5 - 11. It arrived promptly, is a perfect fit, and very attractive, in a rugged and practical way. People notice it all the time and ask about it and think it's pretty cool too. The green stripe in the center is straight and neatly embedded in the black ring, and completely bonded. No worries about the components separating. The trouble some people report with rings like this collecting lint has not been much of a problem at all for me, and anything that does accumulate rinses right off. A great purchase, highly recommended for married people who wish to avoid injury or damage that can occur by wearing metal jewelry around machinery.

Love the colors of the ring and it looks the best out of the other green line rings I saw but ethir the quality check is not there or the quality is bad. This is my third silcone ring and douable the price I have paid for the other line rings, but is right now the worst out of the other 2. Straight out of the package there were two cuts in the green line with one of the cuts almost all the way through. If it was not for these two cuts I would love the ring.Emailed the company when I got the ring, hoping it is just a bad batchUPDATE: took a little over 3ish days for customer service to get back to me, buy is understandable if they are slammed with emails and such. After they received pictures of the defective ring, they sent a new ring out at no charge. The new ring was perfect with no cuts or dings.Left the rating at 4 because of the first issue. If that issue would not have been there it would be a five star product. The fit is nice and has not seemed to loosen after a week of wearing and stays properly in place.

I bought this for my husband to wear while working, he is a tow truck driver and uses his hands a lot.I had high hopes after reading the reviews on this ring, however after less than 2 months this ring has already begun to wear down.There are cracks beginning to form all over the ring (almost like what you would see from rubber when it starts to dry rot)He only wears this while working and immediately removes it when he gets home and places it in our jewelry cabinet.
