SPLENDIDE ….mai più pensiero di bucare la bici

A year ago, I bought a set for my ebike because one of the tubes had punctured on a ride. They hold pressure very well compared with the cheap inner tubes me ebike came with. Only topped off the air a couple of outings this year, whereas the factory tubes were always low each outing. I just bought another set for my road emergency kit. Side note, similar review on the 16 inch, same circumstances, don't trust the inner tubes they use in the wheels of cheap bicycles and trailers.

Never had a puncture yet

I ordered a 2 pack of these slime tubes. The first tube I installed, I put it in the tire, then tried to inflate but it would not hold air. So I took the tube back out and saw that it had 2 small holes. The slime was oozing out of the holes, assumably as it should. However after waiting for 3 days for the holes to seal, they did not. As soon as I tried adding air again, the holes would reopen and more slime would come out. I couldnt use the tube. I requested an exchange. The new pack has worked good, no holes.
