wago-285-181

We snapped the wago-285-181 in seconds.

In order to release the hold you must turn to unlock which makes sense when you say it out loud.
ok fine, its the same action to insert a wire as it is to remove a wire, which seems counter intuitive.

The plastic helix hex head strips out far too easily, and any counter play in the opposite direction results in the immediate destruction of the device.
The mounting tabs are not particularly durable, over torquing a screw could easily tear the tabs right off.

The Tie in Taps seem a bit more durable, but nothing locks them into position, and they are prone to deformation.

Other notes: wago-285-181 is not DIN mountable, the cookies (wafers?) that hold the alignment are not structural.
for a secure fastened connection you'd need a bunch of bolts. The tie in taps partially obstruct the mounting holes,
which is fine, but may cause deformation to the tap, or damage to the mounting tabs.

I can do a more complete write up, with pictures of the destruction, or follow up with some more application specific failure testing
if that is desired.
