Reviewed by Butonit - 31st Dec, 2018 Well it worked as a normal tube would but... Not sure if the Slime worked – Got an in-out hole from a large nail and the tyre deflated immediately. Not a problem as I had some Slime patches etc. to fix the puncture. Problem was that the slime from the tube had gone everywhere, and prevented patches sticking even after much cleaning. More slime would contaminate the patch from behind and it would fail like a wet sticking plaster. I had some other patches (Lezyne I think) which did stick. Tube is now in the wheelie bin.
