I bought some heat-shrink off Amazon once, for an electrical project. I ordered "1cm diameter". When it came, it was 2cm in diameter. I kept it as it was too cheap an item to bother returning and it would probably come in handy some time anyway.

As per your 'warning to others' notion I wrote a review that simply said "Be aware that this heat-shrink is actually 2cm diameter. Looks like someone at Amazon doesn't know the difference between diameter and radius"

Pretty light-hearted, I thought. But I got an email off Amazon saying my review had not been published as it was 'offensive' and 'blah... blah... T&C... blah... blah... no personal attacks'. Sometimes, the hyper-sensitivity of these companies is breath-taking.
