I had a very bad experience with ETRTO406 Tubolito for narrow tires (28x406): 3 leaked slowly without possibility to locate the place where they were leaking because its not possible to put pressure on them if they aren't in a tire (if you try to put some pressure, they explode like a bubblegum).
Tubolito exchanged the two first ones.
The fourth I had died with a real puncture in a type of tires I never had punctures with butyl inner tires previously !? The special patches didn't last long (it was the first type of self adhesive patches, Tubolito has now a new type with glue).
