20 bucks for 60 is pricey, unless you value your time and not having house switch wiring connections come undone (this particular one might not be the right gauge, check before you buy, it's from when i was doing the 3d printer)
There were other problems that made me hate it but how difficult it was to wrap a threaded electrical wire with solid-core romex so that i could twist a wire nut on the end was probably the biggest issue.
I then complained about it in a Discord full of furries and someone pointed me at wago nuts.
have been for ages. they are so good.
did you know you're not supposed to put stranded wire in screw terminals? at least not without a wire ferrule. and lots of other connectors have a relatively narrow set of gauges they're designed for.
but not the humble wago 221. the standard ones around here work for nearly anything up to 4mm², which is just about anything you're likely to run into for most house wiring. they accept stranded and solid wire, they can connect different gauges, and you can redo them. they're absolutely worth it imo
they also come in other styles than the 2-wire inline splice connector shown above btw. there's non inline variants in 2, 3 and 5. i wish they had an 8-10x but i've cheated and superglued two 5x together for that when i've needed one
i was introduced to these at my new job, where we use them mostly for low voltage and signal wires
very solid but they have bitten my finger enough times that i'm naturally wary of them
for low voltage and signal wires, especially smaller gauge, consider Corning Presslok (neé Scotchlok) connectors. they aren't as undo-able as Wago connectors, but they also won't bite your fingers, you actuate them with pliers.
these don't even require stripping the wires.
