I commute on them in the summer months on my fixed road bike. I use Tufo tubs filled with 1/4 of a bottle of their sealant, and carry the remainder. I have yet to puncture, but figured it couldn’t be that different from tubeless that everyone is so excited by.
The very cheap tubs are a waste of money as they have little or no puncture protection. The very expensive ones ditto as they should never really be off the track/closed circuit.
The Tufos weren’t cheap, they aren’t any lighter than the lightest race tyres and tubes (ultremo and Conti) but they do roll better.
