Query: Defective, waste of time and money

I didn't listen to the other reviews, assuming that a few people probably just had bad experiences with the product. I got the tube, put it in my tire and inflated to the minimum recommended PSI/acceptable level of firmness. A few hours later I got on my bike, and the moment I sat down the tire exploded.I found the tear right near the seam, obviously a defective tire. Really frustrated about the wasted time waiting for the tire to arrive, and now having to wait again to find another replacement. Definitely going to spend the few extra bucks this time to get a tube of greater quality and reputation.Don't waste your time buying this tire.
