I've been using these connectors for years and they are good value for the price and quality. One pro tip, invest in a guality crimper. Trust me on this one, or you'll find your self cutting through the heat shrink line on a regular basis.
Solid and excellent for wiring
I bought a few different sizes of these connectors. They are durable and water-resistant. I highly recommend them and I'm planning to buy more for future projects.
