Junk! The terminals stagger, forcing the deer to struggle to make connections. They also don't have enough room to work easily when plugged in, even if the connections were solid. Also, the terminal screws cannot be reinstalled once they have been completely removed (although this is the only way to make a good connection). They also have a very high profile and thickness. This is my most regrettable purchase of the year! Visit the hardware store for better quality at a higher price.
