Hello Steven!
You'll find out when checking the first two characters of the serial number. on the device or on the bottom of the box:
CM = 2020
LV = 2019
BM = 2017
AM = 2015
We already sell it in our web store, so do our retail partners. But make sure to get the new one because they may still sell the model 2019 as well. Requirements are the same as for model 2017 and 2019. Just a hint. I would always go for the latest model. Best regards, Volker
