Voice PE distance?

I am planning to buy a Voice PE (to use with Green + Cloud), but I wonder how close does it need to be placed in order to work well? Will it be ok if it’s about 1.5m from me, and from the side (not looking at it)?

that should be no problem at all , i’ve tested mine at well over 5m

The hardware echo cancellation seems to make all the difference - almost as good in another room as Alexa (and a lot less “ick factor”).
