Looking to donate/sell all my old testing equipment as I'll no longer need it. Nothing has a warranty or guarantee, but everything worked the last time I used them. Here is the start of the list:
Used in lab environment. Works.
BenQ Instashow – two different models (USB-C and HDMI, I believe). In box, works.
Elgato Facecam – note this may be bricked.
Microsoft Modern USB headset – Used often, but still works as new.
