Electronic blood pressure monitor (Fulbourn CB21)
New battery- or USB-powered blood pressure monitor, surplus to requirements. Box battered; includes upper-arm cuff and instructions but not batteries (use 4 x AAA alkaline) nor USB power (fits USB-C, same as most new mobile phone chargers). It works fine but arrived so late that I'd bought a better second-hand model.
