I currently own the larger belt and love it. It legitimately reduces pain and inflammation. That is why I have chosen the pro micro so it can be used on my arms and legs.
At first it was hard to understand all of the instructions and how to set it up. But once I watch a YouTube video on how to set it up I got the hang of it. So far I love it
The micro belt is perfect for your arms my only complaint is the Velcro strap is long and wraps around the device so it’s hard to access the control module
