I know that I have promised you all that I will conduct some experiments but so far I haven’t received my devices. (Sad face!)
Both of them are delayed, even big companies like Apple sometimes have issues during productions so for example Awair told me that the devices are in final process of manufacturing and they will begin shipping in a month. TZOA from the other hand is a lot closer to their initial timeline to deliver their device.
As always stay tuned.
