Bought an $85 Foscam web cam through Ebay. More than 14 days passed from the time I bought it till the time that I couldn't get it working so the seller on Ebay was within his/her rights not accepting a return.
I turn to the manufacturer of the camera (Foscam) who will not furnish technical assistance or replacement for any webcam not purchased through them directly because they contend that there are many knockoffs to their cameras. That's BS especially since the camera itself and the packaging have detailed descriptors of who manufactured it.
So now I have an $85 paper weight. Foscam is a FosScam.
