These connectors are great when you want to quickly splice in pixels or have to replace some bad ones. Simple strip the wire, push in the port and snap the lever closed. When it's night time and you need to quickly replace some lights you will be glad you have them on hand when you are in and out in the matter of a minute or two. When I use them I just keep them in and don't worry about a permanent fix til after my lights are down for the season.
