I don't know how well these are supposed to work. But!! Got a flat in for months! My other bike 1 flat in 8 years and no inserts. and i run the same lines when I the black top. Finishing was the culprit! I must have hit it just right!! I couldn't push the nail through! Now the only gripe I have is that they claim you can ride you bike home with a flat! My but you can!! My rims wuz grinding just walking it home. Wish the marathon pros came in 4"! These inserts and those tire! Hmmmm sound like one heck of a mix!! Gunna give them one more tube try!! Then I'm adding Mr tuffys or Dillons.

Decided to give Tannus Armour a shot after struggling with the mess of tubeless, and not having a compressor to seat the tire. They have been great, albeit a bit heavier than tubeless but the vibration dampening and the rim protection have made up for that! I sliced my tire on a rock on my race run this earlier this season and the Tannus Armour Protected my rim so i could finish the run.(Granted I was riding it well above the recommended run flat speed.) Overall I would recommend Tannus Armour if you want your bike to be quieter smoother and still have flat protection, without the fuss of tubeless.
