TR gives this device 4.5/5.

"Marmitek's Gigaview 820 looks like a serious contender even before it's plugged in. The transmitter and receiver units are nearly as large as the iTrio units, but have a pleasing, sweeping design and a glossy black finish. Rather thoughtfully, the units come with rawl plugs and a mounting plate should you wish to wall-mount them near or behind kit."
