Glad I found these on Smarthome, plus they are a lot cheaper than retail stores.

These are fantastic! They really save time doing wiring jobs. I did a lot of research and, contrary to some opinions, I found them to be more secure than traditional wire nuts. Only problem was that I had to go to another supplier for different sizes. They didn't arrive until 2 weeks after yours. It would be great if you had all the sizes.

I see alot of positive reviews here but I cant agree. These things are terrible. I have some stranded and some solid wire both 12 AWG. I can get the solid to seat properly on the first wire but when I try to put the second solid wire in it is painful. If you push hard enough for the wire to go in it bends. Stranded forget it. It wont take 12 AWG stranded at all it just bends and falls back out. I then tried the wire from the Smartlink switch and that just bends before you can put enough pressure on it as well. I hate traditional wire nuts but these arent the answer for me. Ill be returning the two other sizes I bought since I was lucky enough not to open them.
