Low Voltage Wire Connector No Wire-Stripping Required T and H Type Wire Splice Connectors for Lighting, Toy, Audio, Vehicle Audio, Automotive, Video Uses (Mix 8pcs)

They do what they're designed for. A little difficult to reopen, which is probably a good thing since they won't come undone easily, but you have to get the wires seated just right. I use them for fixing scales when soldering isn't an option. So far they seem to work as intended

One or two of the assortment will be helpfull to your project. The rest can be tossed.Also if connector closes accidentally before using, it is very difficult to open.

Used this product to connect new over the stove range lights. It worked perfect. Was simple, clean and easy to hide. Though I used one connector type the multiple types may come in handy.
