I've been using them since they came out ! although i do use more wire nuts than anything else on small connections(two wire) were i've had best experience with these is four or more wires.. eg.. old work when trying to clean up junction boxes. big splices just aren't that doable. I've used a pile of those six block connectors. best thing since sliced bread. no call backs on anything i've used them on.

i'm buyin... and they'r rated for 20 amps !!!
