Haven’t tried it at the gym yet, but seems very promising!

I can't stand metal rings as my knuckles and. hands can swell when I'm working hard - farmer/gardener/baker. These are so light and stretchy and comfy. Color hasn't faded like some pricier ones have. Even got the wider version for my husband who is a mechanic/farmer. Great value. Looks good and feels good. Can't ask for much more!

The rings are thin and flexible, perfect for wearing, but the sizing enlarged over the course of a few days. I ordered a size seven after following measurement instructuins and all the rings fit well. However, after wearing one I found that it had loosened considerably and could slip off if I waved my hand. Tried it with another ring and same results.I emailed their customer service (email on a paper that came with the rings) and got no reply after a week.I think these are durable and comfortable but they will get lost after the loosening they experience.Update: brought it up to 4 stars because after reaching out several times and having to follow up, thunderfit customer service finally gave me the code to get a replacement of a smaller size. I look forward to it because the thinness and profile is perfect for me.

Thin and comfortable to wear.

I love the fact that I already knew what was my ring size and it fit perfectly on all my fingers,it's simple and doesn't feel tight on the finger

I love this brand of rings! They’re so affordable and I love all the different colors. These thin ones tho, beyond comfortable! You honestly barely feel it and you could easily do 2-3. I’m in and out of gloves all day so I don’t wear my wedding set, these are perfect and I would highly recommend the brand.

I found myself gravitating towards thinner silicone rings, mainly because I disliked the moisture getting trapped under the wider rings, and a small irrational fear of degloving from metal rings. So I've found stackable rings to be perfect, and I bought a few of the popular brands to compare, and to have backups.These super thin rings are as advertised, but they're not only thin in width, but in height/thickness, compared to other brands. This is good for a lower profile and even less noticeable wear, but I actually found it too thin. It was difficult to slip on - other rings are thick enough to roll or slide one, but these were hard to move, I basically had to stretch it and pull into place. It basically looked like a plastic hairtie on my finger.For the price point though I can't really complain, it is an inexpensive backup that comes in my hot dog finger size (10), but I was able to find other brands on sale at a similar or lower cost, and with seemingly sturdier quality. I would say if you like the larger variety packs then this is a good deal, but if you're just buying one or two like me, then look into "splurging" on a thicker ring.
