Once you've worked with this, you won't want to go back to gel wire caps or the like. These devices almost screw the wires together - they don't come loose and the watertight seal is complete. A bit pricey but justified by the content of these products and the level of performance they offer. Especially if you don't have a lot of connections and you want connections to never be an issue, these ports are the way to go.
