Review on FunFitness Bike Tire Lever Set: Premium Hardened Plastic Levers for Effortless Bicycle Tube Repairs - Essential Tool Kit for Road Bicyclists (Set of 3) by Mondreka Rosenhoover

Only used them twice. On the first tire change, they worked as expected. However, the second time I used them, they kept puncturing the chamber when I tried to put the tire back on the rim. After going through two pipes I found that there was a small plastic protrusion on the levers that became damaged/sharpened. In my opinion this is a design flaw. I bought another set from my local Walmart that didn't have this crest on the back of the "spoon". They worked great. FYI my tire size was 700x36c street tires.
