WARNING
These are NOT compatible with the 3005CR klein tools crimper (the red one), If using very thin wire the crimper will not be able to squeeze all the way, I'm using 20g wire and the wire won't get crimped, I had to use regular pliers. The quality looks good very similar to the ones from freight tools, but for some reason the ones from freight tools do get crimped but this ones dont using the same crimper.

Good quality.
Good quality connectors. I use a lot of them so the price was good.

Better than Parts Store Connectors!
I was skeptical at first but after reading so many good reviews I took the chance compared to a a local harbor freight where 10 of these are over $2. They came and I inspected them pretty thoroughly and they’re the same if not much better quality and have crimped on a couple of these to some fix some harness issues on my 2000 Toyota Coupe! Way better value to buy these and get so many where you feel messing up a few of them doesn’t cost you money! Will definitely be purchasing these again for crazy value you get out of them since you get over 200 of them.
