Ideal Electrical Wire-Nut® Wire Conn, Model 71B® Gray, 100/Box

I ordered a generic version of this product from another vendor, and the quality was very bad. The wire connectors did not even grip the wires - they just fell off. I sent them back and decided to order name brand Ideal wire connectors to get the quality. I paid almost as much for 100 of them from Crimp Supply company than I did for 1000 of the generic version.When I got the order, the wire connectors did the same thing as the useless generic ones. I checked them against 100% real Ideal connectors of the same type and color. The real ones worked, and these from Crimp Supply did not. The ones from Crimp Supply were packaged in one of their clear plastic bags and not in original Ideal packaging.I have purchased from Crimp Supply before and have had no problems, but this time it suspiciously looks like a bait and switch. I will no longer buy from Crimp Supply!
