After a lengthy and frustrating return process, the replacement arrived and worked perfectly. To be fair, It took me so long to install the unit that the return window had expired. That was my fault, but they still replaced it. The switch panel controller is a very sturdy aluminum, solid but not too heavy to mount directly onto my golf carts plastic dash. I was surprised by the quality of the individual controller button lables. I initially questioned whether they would really be reusable as listed, but was impressed by the design when I changed a few around. They are a kind of plastic and snap in versus a paper sticker. Each circuit will have the maximum amp fuse installed per the label. You can change them as needed to a lesser amp fuse, but you cannot exceed the listed amp value. Mine is installed on a 48v electric club car ds (iq) golf cart with a 12v step down converter, so all of my 8 circuits have a 5 or 10 amp fuse. The installation was very straightforward. Setting the individual button function to any one of the three modes was simple. Once your done, it is a very clean, professional looking setup. This is a great value for the money because it is so versatile and well made. I plan to get one for my four wheeler, truck, and boat.
