Hahaha, that's a great question! The last time I had a flat tire it was a stupid sidewall slice that the compressor/goo combo wouldn't have fixed. Before that, just an occasional nail that the goo would be perfect for. It's so easy, way better than a spare.
[Didn't you cancel your order or am I misremembering that?]
Yes, I did cancel.
But still very much interested. Hopefully the remaining bugs will be fixed in the 2020 model, or 2021..
