prs transmitter Rf (110068201r) for chem 6c

<p>So from what I've read, this device is supposed to help register students' answers during class...
Anyway, have any of you actually used it? Does it matter which model I buy? Are these the ones required for chem 6c?

<p>i meant chem 6b. ignore this thread! i started the same thread twice</p>

<p>it's used throughout the gchem series, 6A through 6C. physics also uses them, but i can't remember if they're the same model.</p>

<p>i wouldn't suggest buying them through amazon - sure, you might save some cash, but in case they change the model/yours is defective/etc, i think it's a lot easier just to buy this through the bookstore ... or better yet, off an outgoing chem student. facebook marketplace should have a few.</p>
