Nilight 200PCS Heat Shrink Butt Connectors – Waterproof Wire Connectors - Automotive Marine Grade Electrical Terminals – Crimp Butt Splice Terminal Kit

Not much to say besides this is a great set. Comes with a large variety of pieces and gives you a good amount of each. Easy to crimp and does a good job in terms of connectivity

I installed my radio using these bullet connections. I have a crimping tool that fastens the connectors onto the wires for a quality connection. They are easy to use and easy to crimp. They are made out of metal and make a good connection. My only complaint would be to have a greater variety of colors. They function well and the heat shrink protects the connectionn. It's a good product

Most of them work great. The only issues I have had with them is on the female spades they do NOT have strong hold. They pull off real easy. I love Nilight and always buy their stuff but I may not purchase this in the future do to reliability for some connectors. On the plus side most worked nice , looks good and was a good price and the box was nice. Just the fit was not what I was hoping.

Great box of fittings. Above average quality which to be honest is much more than I expected. I've read other reviews that said the box arrived broken. Talk to your shipper because mine showed up in great shape!

1500 parts is a lot you can do quite a bit with this kit

Useful

For the price this kit is fair. Not the best quality some spade connectors were lose and my racketing crimp tool did not get the wire tight enough which is always does on butt connectors from this same company. Disappointed the box came broken but need them that day and will have to live with it for awhile.

I also bought this tool: https://www.amazon.com/gp/product/B07R2MFCQ5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 These style connectors will work with the really cheapie $5 auto-parts-store crimp tool, but those are not the right tool for a good quality crimp. Use a tool like the one linked above and these will do fine. However, I generally pull the plastic boot off, slide the boot onto the wire, then solder the wire onto the connector and put the boot back on. More solid connection, both physically and electrically, and looks better than a crimper-crushed boot. BUT: They work fine with the right tool and the right tool setting for tightness. Granted, I don't use them professionally, but for "backyard mechanic" and most ham radio / general electronics hookup uses, they're fine. That said, the case they come in is cheap, brittle plastic and easily damaged.
