i dont know if these are good tubes or not.

they appear to have uneven sections and bulged areas of my tires once inflated but this seemed to disappear after use.

thin and subject to punctures.

Your tubes are only as good as the tires protecting them. Light, Regular, Premium, or Thorn-Resistant, I have punctured them all on cheap tires. Get a quality set of tires, that match your riding conditions, maintain the appropriate PSI, and they will make you believe that you have awesome tubes. I haven't had any problems with this brand having bad stems yet. If you are getting multiple flats in short spans you may find that there is still an object(s) embedded in your tire or there maybe a flaw in your rims which may need to be taped up. Try to match the puncture in the tube with the section of the tire/rim before completely removing the tube and then do a thorough inspection of both. If you are finding that things are getting embedded more often in your tire compound, you may be due for a new set of (quality) tires.

Bought two and they work, but a little narrow by the valve stem. If you are using with a larger tire, your sidewall may look a little funky by the stem. Thought it would expand out a bit more than it did.

I changed my rear tire's inner tube to this literally two days ago. Today, it is leaking air rapidly. Are you kidding me? Already a leak?
