Works well but slight irritation
I found the band to be really well made and sturdy. The only thing I had an issue with is I found after touching the band with my hands and rubbing my eyes, they would become very irritated. Overall, the product is great and I will continue to use it.

I've lost count of how many I've bought. I've switched to only using bands from now on.

Bands Are Awesome - Customer Service is Unmatched
I've been using different brands of bands since 2020. These are the highest quality and the fact that they offer 32 and 37 in addition to the 41 bands allows me to engage muscle lower in the rep.
