The transfer switch seems to be well made and functions as described, it's very easy to operate when switching to generator power. The two meters on the panel are very helpful as you can watch the load that you are putting on your generator in real time. It is also useful for testing your generator while the power is still on with simply flipping the switches. We were able to connect the transfer switch directly to the main panel with a connector after mounting to wall which eliminated using the external flexible conduit, This made a neat installation. I would recommend purchasing wire identification stickers so circuits are easily identified in the main panel. I would purchase again
