Tsinglax 550pcs Heat Shrink Wire Connectors - Electrical Terminals Kit - Waterproof Marine Automotive Crimp Connector Assortment - Ring Fork Hook Spade Butt Splices（9Types)

This product is a nice product and it’s awesome quality!

Made my solar system easier to set up

The colored plastic did not crack when crimped and the heat shrink worked well. Great idea.

I needed something for my Solar Gen. Project I'm working on & this was perfect in every way... Very nice quality & sorted out...

I can't seem to crimp these without tearing the plastic. when you shrink it the tear opens up and exposes metal. Not exactly ideal. I've tried 2 different crimpers with the same results. Other than that, there does appear to be some weather resistant adhesive on these when they shrink. the only ones I would trust to actually seal anything would be the butt splices though. The rest of them have an open end near the ring terminal, spade, etc. so its almost pointless for those.

easy to install, easy to use & work perfectly, I'm rewiring my boat

Works as it should

They work out great if you’re in a pinch and need to fix some wires
