We have had our share of flats in the last couple of years. In my testing, I have 6 of these glueless patches on my front tube, and some have been there over a year. None have failed .
New flats are always in a different spot.
They are easy and quick to apply, and you can be on your way. Don't change your tube because you have a now have a patch on it. Obviously, we highly recommend them . They are durable, small, have no glue to dry up, and are fast to put on.
