Review on 🔧 Marathon 20990 4.10/3.50-4" Replacement Inner Tube: Ideal for Hand Trucks, Dollies, Pressure Washers, Compressors, Snow Blowers, and More by Andre Pendergrass

I bought 3 inner tubes and after a month or two after installation I noticed that one of the tires was starting to wear out probably due to a small defect. I thought it was my old tube so I ordered another one, replaced it and found the new tube was defective. The exchange took place exactly one month later. Due to the infrequent use, I did not have time to return the goods. In comparison, I bought a tube at a local store for $2 more and it's still alive years later. So I ended up paying double the price. I would not recommend that.
