On Powerpoles I'll vouch that these things are magnificent.

Used 2 on the electronics box in 2009. Worked wonders for making electronics removable. Could connect and disconnect 8 wires in like 1 second flat.
But make sure you get the crimping tool, we made the sorry mistake of not doing so, and struggled with getting them in their housing before putting them in the chassis mount. Otherwise things would've gone much more smoothly.
All in all, great solution if you're trying to make a removable electronics panel or box.
