Query: Total waste of time. Complete failure as a product.

I would give this zero stars if possible. I'll just cut to the chase, THESE DO NOT WORK! Don't waste your money. After patching a tiny puncture the patch failed immediately after applying only 30 lbs to the remounted tire. Removed tire and re-patched using another Skab. The exact same thing occurred. Failure of the patch. These may be cheap and light but they suck at what they are supposed to do, patch an inner tube. I'll probably avoid any Slime brand products from now on.
