EEVblog #1248 – INSANE! A 0.02% Process Meter for $9? WTF!

Dave found this crazy bargain of the century no-name $9 0.02% class multifuction process calibrator on Aliexpress.
Is it any good?
Actually, it’s an AIMOmeter AMPX1 that sells for over $200 on ebay, so what gives?
How can they possibly manufacture and sell a 0.02% class device for under ten bucks?
Teardown time.
