Nikro Reverse Spinning Ball - 861597

Kristy was incredibly helpful!

Worked pretty well, so far at least. This fit a standard 1/4 NPT connection on a 50' hose. I keep my dryer vent pretty clean but had not cleaned it this year and opted to use this. Got out some lint that was in the system. Also used it on the "fart fan" vents, one from a bathroom and one from the laundry room that has a ceiling vent. It definitely gets this out and does push forward pretty easily. I would give it 5 stars but noticed it did not always spin: maybe my compressor would not keep up enough or maybe it just does not always spin. When it does you can hear it. At any rate it pushed debris back which is what you want it to do.
