content: That's a pretty funny item. I can only imagine that it is just a very poorly worded description. Since it contains the 1 Meg resistor, they may expect the buyer to attach the needed drain wire and alligator clip to compete the assembly (or maybe it really is a Bluetooth wireless ESD wrist strap).EDIT: Thanks for the ESD Journal link. Apparently, some vendors are peddling these as a no-ground-wire-needed ESD wrist strap. The item I just saw on ebay explicitly states in the product description "...avoid the trouble of ground cord...". Pretty pathetic claim.www.ebay.com/itm/Cordless-Wireless-Anti-Static-ESD-Discharge-Cable-Band-Wrist-Strap-Slim-New-/270856071888?pt=LH_DefaultDomain_0&hash=item3f1047aad0

content: Now that you mention it, you're probably right, attached to that screw. I just figured the specs were a copy-paste from a real ESD strap.

content: I wonder how many people actually use these placebos and end up damaging something via ESD... as the latter actually tends to be fairly rare in my experience, they might think it's working anyway.

content: Easy way to make it work is to add a little bit of Chernobyl reactor core to it, that way you clean up the core fast and make a good static dissipative area around you.Who needs to live anyhow.........

content: That little plastic box most likly contains a wire and clip for earthing, that way you can walk around until you need the esd at which point you open up the box and pull out the wire and the scurry around like a demented mouse looking for the earth point.On the other hand the box is full of wampum.

content: Ah! These are specially designed high-tech devices, targeting the latest breeds of Electronics Engineers, who think of as an absolute necessity for them a minimal platform of a 32-bit microcontroller with FP co-processor and 3.0 MB DDR5 external memory in order to blink an LED by using the latest ultra HLL compiler (the free version of course, without any code/space optimisations) with the fancy GUI and the magical button that converts their "sketches" into executables for them to upload to their LED driving add-on "shields."I am sorry for the excessive bileshed; it seems that I am not able to help myself with this kind of stupidity anymore...-George
