Review on 🚴 Continental Race 28 700x20-25 S42 Presta Valve 42mm Bike Tube - 5-in-1 Value Bundle for 700c Bicycles by Mike Cassidy

After a few days of searching and reading reviews I decided to purchase Continental Bike Tubes Race 28 700 x 20-25 S42 Presta Valve 42mm. BIG mistake and waste of time researching, I bought lots of 5 inner tubes, two of the inner tubes I fitted to my bike were with a hole (of course I won't know until after the tire is fitted), the third before I after attaching it I decided to let some air in to make sure everything is ok. The picture you see is what happens: the hose exploded due to the small amount of air I pumped into it. I have two more tubes, I'm afraid to use them. I drive about 35 miles every day, the top speed I can get is about 25 mph, I don't even want to imagine what would happen if a pipe burst at that speed. I'm not sure if this is a brand I thought was good but it isn't, or if the seller is selling a used or defective item.
