Conshine 6.35mm 1/4" Audio Connector Plugs TRS Stereo Heavy Duty Style Jacks for Speaker Microphone Cable

The outside fitting and appearing is very good, and that's is only good things about this jack.1. The rubber boot at the end of the jack is a bit small. A bit hassle to fit two 12 gauge wires thru its smaller end.2. The black plastic ring inside the jack's handle is really small, only fit one 12 gauge wire. So it is useless to me.3. The black plastic wire clamp inside the jack also too small. It can only hold one 16 gauge wire maybe.4. The solder taps, I am not sure I understand the logic of this design. There is plenty of room inside but yet the solder taps are tiny....WHY? They are also too flimsy, got bent and broke off so easily...5. The white plastic guide tap is made of some so very cheap plastic that it melted when you solder the wires.I love the outside appearance of the jack but if you are going to buy this jack be aware they are designed for small wire like 16 gauge or smaller and that the plastic pieces inside can easily damaged by the heat of your solder iron.I was able to modify the jack to use but I don't expect it would last long, the solder taps are too flimsy to hold up long.
