Used clicker?

If I buy a clicker from someone who already used it for his/her class, can I re-register the clicker for my class and use it?

i bought used a clicker on ebay and it worked fine. also lent it out to a friend the next semester with
no problems.

Agree - yes, you can use them for multiple semesters / multiple classes. Off Campus Bookstore also sells used clickers, in addition to ebay and Amazon and The SUPE.

So I can use a used ones? How do I re-register a used one for my class? (I found someone who wanna sell it for 20)

Try asking your RA or FA or some students on your floor. I’m sorry I don’t know the answer to your question. Someone else may chime in…

So after purchasing it, how do I re-register the clicker for my class?
