The person that uses this likes it and doesn't even notice it is there. Worn in high temperatures and under gloves and has not complained about any irritation or anything.durable and in many colors. husband lives them. he works in a hospital and uses them a lotGreat product just measurements are off. Orders what it said to and item is way to big. Waiting to see if they send me another size.Using these to replace my tungsten ring that was digging into my hands while lifting. Seem pretty durable so far, but was also about a size bigger than expected. Overall pretty happy with them.Got these for my hubs since his finger was swelling and our other ring was not sitting well and he loves them and the choices they offer to match his colors ?Only received 2 rings, but they sent the rest right away. Great product! Quick response!NiceMy husband love it the fit is true to size and it’s comfortableI wear them because I work as a mechanic and I am not allowed to use any metallic rings. They are a safety concern. This allows me to wear a wedding band while I work. These bands let your finger breath better and are more resilient than others I've used in the past.Great product, feels like good quality however I ordered a size up (as per the fine print) and it was a little too large. Emailed the customer service address on the info in the package and they would not help with replacing it as per the advertisement says. Customer service is terrible and should be addressed from Thunderfit. Looks like I will be finding a better brand that sticks to what they advertise. #falseadvertisingI got these rings because I had to replace some lost ones from another set. My only suggestion is to size down. My ring size is 12.5 and that set was constantly falling off as it is designed to fit 12.5-13. With these 11.5-12, the rings are snug and comfortable. Will buy again!Great ring, fix as expected, very light weight, you don’t even know it’s on. Great for work or working out.Very happy to get these and they fit perfectly
