Review on Technology Research 40100 Automatic Transfer by Maurice Strawther

Update May 7th 2016: I used some rubber washers I found in warehouses to put them behind the mounting holes of the device, and now you can only hear the hum if you stand directly in front of it and try to hear it. It's been in production for about a month and I had nothing to worry about. Works 100% as expected so far. I also posted a photo of what the real block looks like. I've added a volt meter to the front of mine so I know what's going on, so don't expect it when you order it. The device is actually made of plastic. The EMT holes are pretty far from anything you can mount it to, so you'll have to bend the tube to fit these holes. I drilled new ones below for a cleaner install. The device has a certain weight, but gives a high-quality impression. The device emits a low hum. Nothing too crazy, but still a thrill. So far my device has worked for about 24 hours. I will post an update if I encounter any problems. From now on, this unit will operate 24 hours a day, 7 days a week.
