Worked out great. My fiance who's never done anything with bikes was able to figure it out in one afternoon.

Perfect

I’ve never seen tubes this cheaply made. They don’t have the powder like most other tubes. I used baby powder to help install them. They also have a weird, shiny rubber. They seem to work okay. Time will tell how durable they are.

I have to preface that I've only had one on my bike for 3 days now, but overall first impressions are great. Tubes are a perfect on the rim, and the install was super easy (once I finally did it the way I was instructed to instead of going rogue and doing it another way). If it comes down to it that I have to purchase more, this will be my first stop. Although that of course is dependent on my 2nd and further rides.

I installed the first tube and after two rides it was flat. I filled the tube with air and submerged in water to see where the air was coming out and the seam opposite the valve had split. Clearly not a puncture but a manufacturer defect. Terrible quality. I just put the second tube in but have very low expectations it will last very long. Would not recommend this product at all.

installed tubes but after riding only 20 mins., then overnight one tube was flat. after pulling the tube out, this found that the rubber had separated in a circular pattern on the backside of the valve stem. the tube is now patched. I'm waiting till morning to see whats what. i got what i paid for....still, I'm not happy
