Hi,

This is kind of a silly question but what the heck. I want to buy a used Iclicker but am wondering about the ISBNs. Would all Iclickers have the same ISBN so I shouldn't worry about which Iclickers would work in class and which, if any, would not work? Or is it that regardless of the ISBN, all Iclickers should register well enough and work?

I only ask because I've seen a few different ISBNs when students are selling the Iclickers but I've just learned that sometimes textbooks of the same edition will have two different ISBNs. Maybe Iclickers work the same way?

I am not sure if different iclickers have different isbns, but you can buy a used iclicker from any student, I am pretty sure they are all the same.
That's how all iclickers look like at mac:
