Review on Mxuteuk Closed Connector Connectors Terminal by Tim Harrington

I have never used this type of end cap. Because of the Revain's good review, its transparency for wired viewing, and of course the low price, I bought it to try. Well, very disappointing. Three main problems: 1. Impossible to pull the wires together. When I put it on I didn't feel enough tension and noticed that the cap started to twist as I twisted it. I opened it up and noticed the wires were still disconnected. 2. In the cap, the twist lock does not stay in place. Note that the lock has been moved to the rear end of the cap (the photo shows a dark cylinder inside the cap. The left one is new, the right one is broken). 3. Perhaps because of him, the cap dangles and does not stand still. I can easily take it off after "rotating" it. It's dangerous, and if it comes off, it's very flammable.
