Review on Oxbird50X-2000X HD USB Microscope for Adults - Digital Microscope for Android Phones (non-iOS iPhone), Mac & Windows 7/8/10 Compatible by Jacob Morrison

Pictured is a 1/8" drill bit and reed switch (short video) as I drove past it several times with a magnet. Every parent has to click the 'Buy' button. Can see the horizon of one to expand young people to science ok its not all roses the base and armature are cheap lightweight plastic you may need to either clip or glue/glue/velcro the base to something sturdy or it will. As for the people complaining that it doesn't work with their PC, visit their website, download their software and it works great with their viewer.
