I have pain in both legs. Do I need two devices?

Generally, our users find that one Quell device is sufficient for their pain relief needs. 

The customer should try using a single device first and ensure it’s calibrated properly to maximize therapeutic benefits.  However, if a user feels like he/she could benefit from getting a “higher dose” of therapy by wearing two devices, they may do so. Devices should be calibrated one at a time (i.e., only one device should be on the leg and operating).
