Hubby was happy
Giving these another try as the last flat was caused because of the valve seperating from the inner tube , did not over fill and there was no puncture in tube or sharp in tyre

Decent quality at a good price - size is correct.
Managed to navigate the confusing multiple systems for describing tyre size, and ordered these. The tube is labelled much as the original tube was, and appears to be of good quality. Diameter is perfect. but cross sectional area is much smaller than the old tube. I assume that the old tube has stretched over the years and installed the new one. Early days, but the tyre is fully inflated a week later.

Great inner tubes
Gets the job done. Replaced my inner tubes after a few years of use which I should have done much earlier. I've had them for a few months now and haven't needed to pump the tyres at all. Previous ones kept passively leaking after a few punctures which I had to repump every few rides.
