This connector has one potentially fatal flaw, plus a few other weaknesses.
As always with uncertified connectors I do not recommend that these get used in safety critical situations or where liability could occur.

This modular connector system is quite neat. It can be stacked in various combinations, and the one connector acts as both plug and socket with shielded contacts on both sides.
The primary hazard is that these connectors are not keyed, and can easily be plugged in out of alignment, resulting in a risk of shock or equipment damage. That is a significant concern with users who don't understand the potentially fatal implications of an incorrectly mated connector.

In the pump scenario I describe in the video, if a maintenance operative was holding the earthed/grounded enclosure's door open with one hand and reached down and grabbed the pump with the other it would potentially result in a sustained and fatal shock.

A secondary issue is that the wire retaining spring is not linked to the metalwork in the same way as a Wago style terminal, and relies on plastic to hold it in place. That means that an arcing contact will potentially melt the plastic and loosen the connection further.

The connectors could have genuine uses for personal experimental projects, but I wouldn't recommend them for use in a professional environment. I'd also advise that they are only used at low current, as the mating area is quite small and of unknown pressure after the contacts have clicked past each other. Any contact heat will make the contact pressure worse too, due to softening of the plastic housing.

In summary, it's quite an interesting connector with a lot of potential uses. But it has its limitations.

I've only found one seller of these on eBay so far, but others are selling them on AliExpress. The item code is DF-2604D:-

This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
