Where not dumsnål.
Add a few hundred dollars and buy something properly.
Had my system (two M5, the M3 Link Mate and Hub) in almost half a year.
The sound? Njaa, OK. You can listen to, but not great. Gets very tinny at higher volumes.
App? Completely useless. Has managed to connect my devices to surround two times. The remaining times you will not speakers.
These were supposed to have as a supplement to my "real" system, but has only caused hair loss and frustration.
Buy Sonos, or otherwise. Buy a Pringles tube, cut out of your phone and run, it would baskemig be better. Then you get the addition of chips in the bargain.
