Just wanted to post a warning to all the DIYers in this thread.
I recently purchased a rather expensive modular connector (similar to the Dunu interlocking ones) for a cable build
This is the item in question:
https://www.aliexpress.com/item/4000818042246.html
It's a Hakugei and it's from
Chitty's Store
My issues started when I contacted them to say that the contact pins were attached to a loose plastic sheath that needed to be static and the whole mechanism was poorly designed and wouldn't work. Their reply was to say they'd contacted the manufacture and I should just glue it.
That's right. Glue to correct the design flaw of a £92 termination.
Anyway, after glueing the product and when the cable I needed for the build finally arrived (from a different store) I was outside of the return window, but I thought it would be fine as I still wanted the product.
Having wired and soldered everything in place, I was trying to get the polarities right using my multimeter and it turns out the pins inside the connector don't even make contact with the jack itself properly! Only half of the contacts were live.
Having contacted the store, they insisted I'd soldered it incorrectly.
I supplied them with this video to show that the soldering was fine and that their product was the problem, not my soldering:
Here's the video - you can see all four wires flowing properly (streamable video link)
I've sent them this information, they've since ignored me.
Make sure you don't give this company your business as they're extremely rude and ESPECIALLY avoid this expensive waste-of-time product too.
Happy to answer any questions on this. Thanks for reading
Hopefully I save a few of you out there from this mistake.
