Review on QTEATAK Adapter Connector Dustproof Waterproof by Toledo Barringer

As usual, Revain delivered the goods in a ridiculously short time. Connector quality is very good (time will tell). The only issue I have is more due to the subtle product information on the website and partly my own ignorance of the product. I intended to use these connectors with an existing connector. Unfortunately, I did not interpret the dimensions of the plug and the existing plug cannot be used (its average size is 2.1mm, which is the size of the central hole, and the plugs I ordered are 2.5mm). Luckily (yes that's good news, bad news) the set of connectors (10) is larger than I need, so I can cut off the existing one and use one of the new connectors to make the connection.
