In my opinion the weakest part of the system is the rubber flaps; they’d regularly get clogged and impede proper release of air. The valves included a thing plastic “plunger” to open them but they’d sometimes work themselves loose and then you’d completely lose the ability to remove air from the tire without inserting a spoke or something similar in after removing the core.

Tyre sealant is a little like blood, in that sealing particles are suspended in a solution inside the tyre and get carried to any hole and congeal there to seal the opening. “The solution pushes the nano-platelets into the hole, which builds up in layers, so it plugs holes that are over 3mm wide”, explains Tom Makin from Peaty’s.

Most sealants use the coagulating properties of natural latex to clog punctures. Latex is a dispersion of polymers (long-chain molecules) in either water or a water-based solution of ammonia. Inside a hole in the tyre, the air pressure drops and there is a rush of air. This causes the water/ammonia solution to evaporate, leaving the latex molecules to coagulate (knit together), plugging the hole.
