I bought this to prepare for working from home around the time of the coronavirus, but I was soon required to go back to the office, so I never had a chance to use it and it's been stored at home ever since. I purchased it on Amazon for 14,980 yen (please see the screenshot of the receipt). I think it's a highly functional and perfect partner for web meetings, so I hope to pass it on to someone who needs it.
