I’ll explain why later in this post, but as part of our poultry keeping kit I felt the need for a very precise set of scales. Something like a laboratory balance. And indeed I eventually found exactly what I was looking for on eBay.
But imagine my surprise when I first did an eBay search to find around two and a half thousand sets of precision scales for sale. There couldn’t be that high a demand for weighing jewellery, lab samples, and suchlike, surely?
