Product review (1 stars): Broken in the wall
I bought 2 kits to reach the outside of the house. I think that must have been too long because as soon as we added the second kit the handle part started twisting but the whole thing wasn't spinning, this caused the handle to break off. Luckily the break was in a spot we could reach with a long pliers. When we pulled it all out there were spots closer to the brush that were twisting. So lucky it didn't break at a point closer to the brush we wouldnt have been able to get it out of the wall.
Over all this is a terrible product that should advertise that its NOT recommended to use more than one kit. They seem to break when you add the 2nd kit per most of the low star reviews. The handle is thin plastic and it cant handle being more than 12 in length.

To get the big clog of lint left by pulling out the brush before it got to the end, we blew the vent out with a leaf blower.
