Review on Absolute USA SPL2218R 22/18 Gauge Scotchlock Quick Splide Auto-TAP Connectors: Excelling in Secure and Fast Wire Connections by Luke Cotton

Found out these are not original 3m but a cheaper fake. The metal protrusions are very weak and often flex rather than penetrate the wires, resulting in no contact or intermittent contact. I had to replace a few wires that weren't pinching or cutting into the wires I was trying to splice. I've been using these types of connectors for years, so the problem isn't how I use them, just that they have weak stems that just bend and won't go into the wire housings. I have installed car alarms in the past and have used thousands of connectors of this type. I will not order this brand again. Pay a little more and get a higher quality 3 meter faucet.
