Review on Optimized Mountain Bike Tire Liner and Bicycle Tire Protector – Fits 24", 26", and 29" Bike Tires by Amrozi Goodall

I've had 2 flats in about 4 months so I put this product on both the front and rear tyres. A month after installation I had a doubly smooth ride. Then over the next 5-6 weeks I had two more flat tires on the rear wheel. I removed both earbuds and haven't had a single bowl for two months after removing them. Coincidence? (FYI, I've checked the rim and tire tread for dirt and other objects with each firmware and replaced the punctured tube with a new tube each time.)
