I have used several different styles over the years but all have had a major problem but this one has not. They all had only one connector on the back. The additional grounding plug on the bottom makes a big difference. Otherwise, they all come loose when more than one or two plugs are inserted. the weight of what is connected is too much for them. it's stuck with two behind and won't budge! I have a box of those disappointing old single fork styles that I threw away after getting these. since I've ordered two more and couldn't be happier! Fyi also seems to be better than average quality.
