These rings are attractive, durable, and breathe well thanks to the grooves on the inside of the bands. Other rings that I ordered in the past left a white sweat ring on my husband's ring finger, which actually began to get sore. However, the thunderfit bands I bought for him allow his skin to breathe and are far more comfortable. My husband works on a drilling rig, and works with a lot of harsh chemicals that can be extremely hard on his hands, as well as his wedding band. These are durable enough that he's had the same one on for almost two weeks, while other brands we have tried only lasted a couple of days. They look very pretty as well. These rings are an excellent value for the money. I will definitely purchase again in the future.Note: If you are considering ordering these for someone who works with their hands a lot, consider ordering up a half size. My husband's hands swell a bit while he works with them and the ring fits a little tighter. He reports that though the ring is still comfortable, it might be nice to have a slightly bigger size for those times.

Love these rings. I’m an automotive technician so my hands get dirty quite a bit and are exposed to harsh chemicals. I’ve been wearing the same ring for the past 5 months and it still fits snug and hasn’t torn. Definitely recommend if you have an active lifestyle or work a trade.

These are the only rings my husband will use. He loves them, and loves that they come in colors that go with everything! He says they are very comfortable and great quality for the price.

I’m 6’1” 259 pounds. The ring is completely comfortable, durable and stylish. I have big hands and a size 10-11 worked perfectly for me. Now I can go to the gym with confidence and not fear or Scratching my current 14 karat gold ring. I’m glad I decided to invest in this gem.

I've been wearing the same band for months and it looks like new and fits perfectly yet. No stretching and it feels so comfortable. I farm and didn't want to lose a finger so I got a set of these. Perfect.

I have waited to review this as I couldn't believe that this would last very long. My husband works construction and never has his wedding ring on as it has been damaged once already. I purchased this for my husband last November when we went on a trip to Hawaii and wanted him to wear a ring. He hasn't taken it off since! This ring is so comfortable but better yet durable!! I would have never thought that a rubber ring would look and feel great but it does!!

I have ordered various silicone rings from different companies on Amazon, based on my experiences, I find ThunderFit rings to be the best value for the money. Outstanding customer service if any issuesever arise, as well replacing the wrong size. They just send you another set at no extra charge. They truly just want you to be happy with their product offerings. With that said, I have ordered other "High End" rings with claims of a 94 year warranty. Not so Groovy either. Their customer service simply was very disappointing. Honestly, I could not tell the difference in quality. I feel like you can pay more, but you're not going to find a better ring than the offerings from ThunderFit. You just need to find the right size, width, and style best for your finger. I hope this helps you bypass all the hype that the high end sellers are trying to scam you with. Medical Grade Silicone is pretty much all the same material.

UPDATE:So I ordered another set because the first set was just too tight. Following the sizing instructions, I ordered what I thought would be the right size, but now they are a little too big. But honestly they work and achieve what I was looking for. Measure the circumference of where you want it to sit, then I would go down a size.I still do not believe the grooves inside do anything. They do not improve airflow under ring or drainage of water.The appearance was better. No flow lines on this set. They still are the most metallic appearance I've seen.Previous review:I had purchased these because their "metallic" looking rings looked the most like metal of all the silicone rings I looked at. But when I received them, you could see the flow lines where the pigment wasn't dispersed within the ring on two of them. This makes them look like cheap rings.I am a probably like a 7.5 size, so a 7 feels a little tight. I tried to stretch them per the included instructions, but that really doesn't work and I ended up breaking one of the seven.The breathable grooves don't really do anything for the comfort of the ring. I thought it would make them feel more comfortable, but it really doesn't.The good thing is you get 7, so you can have fun and change them up depending in your mood or what you're wearing.
