Did you use spades with your Furutech outlets?

Stab connectors are a bad idea...the connection point is narrow causing  higher failure rate over time from oxidization and conduction thermal heat. The only one that loves them are contractors wanting least labor cost. Positive (clamp) pressure with wide surface area contact is always the best

for minimizing oxidization  and thermal  heat issues over the lifetime of the electrical outlet. Let anyone who advises you otherwise

pay your homeowners fire insurance.

Yes, back-stab connectors on bottom shelf receptacles are bad news.  But while the back holes in the above receptacles appear to be back-stabs, they are not.  They are alignment holes for the side-mount screw connectors.  Several good manufactures make this style top shelf receptacle. This style is my first choice.

Got it, looked at the internal video, you basically have to back the side screw off, insert wire then tighten the screw so that the internal plate clamps

on the wire... not a stab connection.
