I bought a pulse oximeter on Amazon for corona measures, but it seems to have been a Chinese trader, and I was deceived because the product did not arrive. Therefore, we purchased the pulse oximeter "OXIlook" sold by a company called FUJIKON in Japan again from Rakuten Ichibo.
I was deceived by a Chinese trader on Amazon, so I re-purchased "OXILOOK", a pulse oximeter for corona countermeasures from Rakuten, from a Japanese distributor.
