Clone of Wago product that Wago don't even sell???

This is bizarre, but strangely useful. It's a Wago-style connector, but in a form that I can't immediately find online. As if a company ripping off the Wago design has introduced a completely new product. If it is a new product then it's actually a really good idea.
Perhaps there's an approval issue with the risk of water ingress initiated tracking, although there are clear barriers between adjacent contacts and the spring mechanisms actually move down to create a greater gap when wires are inserted.
As always with clone products with no formal testing, you use them at your own risk. Although these connectors seem well designed, it's just an unfortunate byproduct of society and its many made-up jobs (inspectors of inspectors of inspectors) that if a fire occurred in your home, then even if these were not the cause, there's a risk that some officious clown would use it to void an insurance claim. (Usually because they're employed to void insurance claims.)
It's also worth mentioning that if you use real Wagos you will get predictable results over time without the risk of a clone factory cost-cutting to the point of making dangerous copies.
John Ward tested one of the Wago clones vs the real thing with very high current:-

The discovery (additional bit of video at the end) that these use tinned copper for the electrical connections suggests that they are actually quite usable. Looking at John's video it suggests that the very modular approach of the Chinese design (individual steel springs) versus the original Wago units with a different spring assembly for every multiple of ways may have made this neat variant easy to implement.
