Crimped properly, never had a problem with them on fixtures.

That's the key. But many times they appear to be crimped and still fail and required fiddling with. We tried doing the end to end fluorescent thing Don mentioned and after going back to open enough lights to mess with them, we decided that it was just faster and more reliable to use a wire nut.
 
Back in the mid 80's through mid 90's the 560's (14 awg) and 562's (12 awg) were pretty much the standard for pig-tailing receptacles in residential.
I installed many thousands and never had any call backs.

Occasionally when I did service work I would find failures at homes/apartments I had not wired. The failed connector obviously did not get crimped correctly. The blade would be bent or at an angle so not solidly connected to the copper.

Prior to the IDC connectors crimp sleeves were used for pig-tailing. Those failed all the time. When they failed they usually produce enough heat to burn the insulation off every wire in the box. When the IDC's failed I never saw and melted insulation. Just a burn mark at the connection.

I'm not sure why but I had never seen receptacles used as the feed through device unless installed by a DIY up until recently. Even the production/tract contractors always pig-tailed everything. In recent years some of the new generation of production EC's that primary employ unskilled workers don't pigtail.

Back when Walmart had suspended ceilings, and end to end fluorescent feed through fixtures, they switched fixtures on thirds. Back then, you could still share the neutral, [color=red[ and not have to use a three pole breaker. [/Color] Anyway, we would use those to make the ballast connections. Two people on a scissor lift would drive at a constant speed down the rows, one driving, one making connections. Usually could do an entire store in about 8 hours.

And you still don't have to use a three-pole breaker....😉.
