Review on Insulated Terminals Electrical Connector Assortment by Zachary Greene

Metal connectors are too thin and plastic is brittle and breaks easily. Yellow connectors do not hold the wire securely. The metal is too thin, and as soon as I loosen the crimp, the wire comes loose and presses against the thin metal connector, releasing the crimp. The yellows literally dropped the wire under their own weight. The blues is holding up a little better. I managed to break through the rippled blues, but it took some effort, but not excessive; they should not diverge at all. The reds are doing well. BUT plastic tends to crack so the connector needs to be wrapped in electrical tape after crimping. The bottom line is, save your money and don't buy these.
