Why I Love This 6mm Ring More Than Other Silicone Rings

Honest review of Thunderfit ring.

ThunderFit Silicone Wedding Ring for Men & Women Demo

Top reviews

Harry Mercado
The women’s Thunder-Fit ring I received was exactly what I expected based on the description on the page. The quality of the silicone ring was soft and a true black color. I was very happy to receive this. The ring was very nice and comfortable to wear.I did have one issue with the ring though, it was just a tad too tight on me. I am about a 4.25 in ring size and I ordered the 3.5 to 4.0. I ordered the smaller size based on previous reviews, thinking that the ring would stretch. After wearing it for a couple days it wasn’t comfortable for me, and it did leave a little bit of a red mark. Instead of waiting too long to see if the ring would stretch out (which it could possibly still do… I just didn’t want to wait too long in case there were exchange or return deadlines), I decided to try to exchange it for a size up (the 4.5 to 5.0).Jodie from Thunder-Fit was wonderful to talk to. I reached out through the Amazon app and she responded within a day of my inquiry to exchange the ring. She actually told me that I didn’t have to send my original ring back. She made arrangements for me to be able to get the ring that was one size bigger. Now I will have two rings to see which one fits me better. This is a great help because if I end up purchasing a ring in a different color, or a spare ring, or if I ever need a replacement ring, I will know for sure which ring size fits me the best.I feel that this was a really great product from a great company that really stands behind their product and is willing to do anything to make their customers happy. There are not many companies that I can say exemplifies these traits. I would definitely buy another product from this company. I would even buy one of their men’s rings, but unfortunately the smallest size is way too big for me. If they ever go as small of a size that fits my approx. 4.25 finger I will for sure buy this style of ring for myself.Now I’m wanting to see what other colors I want to purchase…;P

I haven’t worn a ring in over 15 years for several reasons. One I can’t for safety reasons because of my job and hobbies as I like having all 10 fingers. Two I am often work in crop fields so I wouldn’t wear one n those days so I wouldn’t lose it and thus not think to wear it on non work days. Three if I am sitting dow not doing anything it takes extreme effort to to fidget with something and I got tired of being told to stop as when I am an adult. I fidget with pens or whatever is in my pocket without even thinking about it. I don’t like the wide bands over about 6mm(1/4 inch) as it annoys me when I bend my fingers. It is almost impossible to find bands under 7-8mm wide above a size 10. You can’t convince me it is because of strength as I have worked with many O-rings and gaskets that are much larger in diameter but are much narrower. I was then pleasantly surprised when I found these. These are and are good quality. When sizing I will say make sure you pull the paper or string a little snugger than you think you might need to. I measured out to a 4mm wide size 14 on how I have done it before but it was too loose and would catch on my pockets and move constantly. Also after a couple days it stretched just a bit but was noticeable to me. So I ordered a size 13. The size is much better as I barely noticed it after a couple of hours. I didn’t try the size guarantee they offer because I wanted to try the 5mm wide band. I may order a 4mm size 13 after trying this one for a week or 2. I know 1mm is not a lot of difference but it can make a large difference in feel.

My husband wears these rings and is in the construction industry. They hold up quite well, and are very comfortable for him.

The product came on time. The ring came in slightly deformed, but when you wear it, it quickly adjusts to your finger. The product is true to size.

Joshua Green
Colors are subtle, the thickness is appropriate, and the material is durable. Great gift for loved ones

Jay Washington
These are just the right thickness and the sizing seems very spot on. Great for working men.

When I first got the rings I thought I wasted my money. I gave it a chance and this is helping me get over my ring issue(s).I had not worn a ring for the first ~50 years of my life. I got married and bought a 9mm wide tantalum wedding band which I wore daily and had trouble feeling comfortable.I bought these rings thinking they would be hard silicon just thinner than what I had, but they were soft like what felt like a rubber band. I gave them a chance and wow, I am actually able to wear them 24x7 and my wife is happy, which makes me happy !they fit true to size, I wear an 11.5 and purchased an 11.

These are cheap and do their job. But don’t last long. Stretched out and started wearing away. It’s nice you get a bunch in the pack because you won’t be wearing one for too long before you need to swap out for tightness
