It lost connections, had unclear sound, was unreliable during conversations, had static.

Other times the device loses connections but since I have tweaked my AC1750 Router it seems to be better.

One does need a fast Internet connection to use this device.

though...it sometimes seems to nudge my connection enough to disrupt if Im watching a stream video on my Ruku

Loses connection at some point every day, does not keep the line up for long at all
