I have owned sets of these for all of the boats I've ever owned. They make it super simple to organize connecting wires into one place. Each positive and negative unit holds up to four wires but you could probably add more if you were careful. I've not ever needed more than four so have no experience here but as long as the additional wires were smaller, you could add them. This makes it super easy when connecting all of your electronics and since mine come off my "big" motor cranking battery each winter, it's very handy to have these little units. Solid brass construction where it counts and positive screw in connections. Perfect for any boater who has multiple wires that need to be connected to a battery. Highly recommend!<br /><br />All opinions expressed in this review are my own. Product ratings are based on performance, durability, construction, and overall value.
