Purchased these along with the wirefy ratcheting crimpers and their heat shrink tubing and I'm glad I did. Used in conjunction with one another these products offer, in my opinion, an extremely durable , incredibly secure wire connection. They don't do anything extra or special but they do what they're meant to do very well. No more worrying if my butt connections are going to pull apart, corrode, or fail. Crimps are uniform and tight, connectors shrink and seal for a watertight connection, and the heat shrink tubing is cut to a prefect size and seals over the connector very nicely as well. Very pleased with all these products. I used these to re-wire my semi truck's headlights and taillights. A head or taillight out can result in loss of revenue, time, and can often incur fines. With these wirefy products, I'm not at all concerned about any of that. 5 stars and they get my recommendation any day.
