Keiser M3i

I recently bought a Keiser M3i with the M Series Converter and Polar HR monitor. I am able to use Zwift and have been for the past month. Receives Cadence, Power and HR. Seems to work pretty well as long as you limit the number of bluetooth signals only to the one computer (I use MacBook Air hooked up to a monitor) that is operating the Zwift program. You can use the Companion Zwift app on another device (iPhone) as long as you use wifi (same wifi modem as computer) and disconnect Bluetooth. Simultaneous bluetooth signals cause your ride to stop intermittently during the ride which is frustrating.
