No Complaints
I'm a fairly new rider, but I'm satisfied with these tubes. I ride a MTB and I got these for my commuter tires. I don't have any complaints, and I plan on getting more of these tubes for my main MTB tires.

Don't be put off by seeing "26 x 1-1/2" as it's the same as 27.5 / 650B / 584MM. These tubes fit great in my 42-584 tires.

almost a proper 650b
Built 650b wheels and had to resort to 26" tubes - pain to mount but otherwise usable. 29" definitely too large - the slack would bunch up. Would be nice to get proper 650b in correcct size but this one will do. Using it with 2.1 tires. Hard to predict reliability yet (it's streched out so who knows).

PROS: Easy To Install

CONS: Larger Sizes Out Of Stock

Kenda Tube
The tube I received (smaller diameter than I ordered!, not that it matters all that much for tubes) is marked Kenda on the tube itself. As I've used Kenda tubes before (and paid about double for them from lbs), I was pleasantly surprised. Have about 75 all mountain miles on it so far and it's performing as expected. Weight is below average, but that could be size related. Valve is very good.

Looks may be Deceiving
I bought the wrong size. The photo of the product online made it appear that I was buying 1.5in wide tubes but that's not what arrived. Make sure you select the correct size.
