I have one and have mixed feelings.
If you value convenience over performance, this might be for you.
Once installed, operation is easy and performance is not bad for an omni-directional fixed antenna.
BUT....my unit was noisy and the motor sounded labored during part of it's rotation. It only lasted 3 trips before it failed completely. Winegard was excellent to deal with and replaced the dome. The new one worked a little better than the failed one but it still sounds like it is "binding" during part of it's travel. It hasn't failed completely yet but I have my fingers crossed.
I'm not a big fan of CW but they have them on sale for $100 off occasionally.
