Review on 🏻 Iellevie 26x1.9/2.125 FV Threaded Presta Valve Bicycle Tube Inner Tube - Pack of 2-2 Free Bike Tire Levers: Durable and High-Quality Tubes for Optimal Bike Performance by Warren Hess

Not much experience buying these cameras. It's a bit difficult to attach the tube to the rim and get used to the Presta-Valve system. A week later, one of the tubes couldn't hold the air and collapsed overnight. This necessitated the purchase of another camera, this time from Walmart. The Walmart tube held air and didn't collapse. It was also difficult to inflate the tire as I had to purchase a stem adapter to convert the Presta valve fitting to regular threads.
