Just like the ones that come with the original OT monitor. They are a bit shorter than expected, but fit well all the same.

### ⭐⭐⭐⭐⭐ Perfect for most people
*by D***S on May 25, 2025*

Great ! The orange one is very small. The black one fits perfectly at the max on my bicep. If you have 16.5 inch biceps or bigger these won't fit you
