Great in wall wire, easy to install
Size: 14/2 AWG-200 FT, Color: White
Ran this through studs for an in-wall 5.2 system, worked great, very easy to fish, wire threaded nicely, good copper, good connections. Easy to bend for 14 AWG.

Parts actually fit 11S.
Size: 23 Pack
Bought replacement parts from another vendor, but the brushes are nylon and do not last. Filters did not fit 11S, so I had to throw them away. Parts from this current kit fit perfect, brushes are rubber and seem more sturdy. Have not had to change them yet, but there were 10 replacement brushes in the kit, as the other kit only provided 4. Changed the filter also, picks up a lot more dust and dirt.
