When I read the other reviews I thought so bad it will not be all right. So ordered, received very quickly unpacked and get the first positive impression about the good workmanship. Power off by backup and attached the rack, power and oomph fabricates an arc ..... As mentioned by previous reviewer the aluminum edges are sharp and cut the cable. Remedy brings an additional application of heat shrink tubing ....... The cable routing should be improved! It would also be a colored neon lamp or LED tube as a light alternative well .....
