This little device is an incredibly useful tool for getting numbers off tiny surface mount components, but as supplied the focus had been locked to a very close position, making it tricky to get close enough to some components to see them clearly.
This video is a quick look at the insides and how to adjust the focal distance by turning the lens in its threaded barrel. Unfortunately this is not made easy by the lens being locked with glue and access to the insides being made difficult by hidden screws under awkward self adhesive panels.
If you want one of these then here's a link to the item on AliExpress (not a sponsor).
This is an affiliate link, but that will not affect the price you pay. (But feel free to shop about.)
Some listings don't show up in all countries. Suitable keywords are 2.8" digital magnifier.

Supporting the channel with a dollar or two on Patreon helps keep it independent of YouTube's quirks, avoids intrusive mid-video adverts, gives early access, bonus footage and regular quiet Patreon live streams.
