Second this, *do not* use the "push wire" type connections, they are the
ones with the little release slots next to the holes. Do not however
confuse "push wire" with "back wire" as they are not the same thing.
With the better spec grade devices you will find many offer the "back
wire" option which is a screw clamp type connection that works well and
saves you the fuss of wrapping the wire around the screw. I've become a
fan of these back wire clamp connections, particularly when using
stranded wire pulled through conduit, where the back clamp eliminates
the hassles of stray strands popping out from under the screw when you
try to do a wrap around connection.
