"The description doesn't state, but you get a 100m roll. More than you'll ever need unless you're installing bells for a living. The wire is two solid cores so not as flexible as some wires, and does seem to get tangled quite easily.
can't comment on performance or reliability until I actually get a bell connected to it :)"
"this wire looks OK until you use it. The wire is solid and very light gauge so when connecting it it breaks very easily. Every time I tightened the screws of my bell push they broke the wire. Get a heavier gauge wire if you want trouble free installation!"
