I purchased "90mm" Posts. They arrived and they are only 82mm. Website advertised +/- 5mm tolerance. They are too small for my 90mm fittings. Even after supplying evidence, the owner was uninterested and even went so far as to change their website to 6mm as part of their defense! As I had a taken screenshot before contacting them, their dishonesty was not only obvious, but also irrelevant as they are too small even at the doctored tolerance. Luckily, my order was small. I don't recommend them.
