Nate,Hello, Nate from TFTestkits here. Please shoot me an email (if you have not already) at [email protected] with your order number and I will remedy this ASAP. Sometimes the stir bar can fall underneath the foam insert, so you may want to check under it as well.
I received the magnetic bar for stirring, thank you! Turns out, after I showed the bar to my wife...she sheepishly looked at me and admitted she opened up my kit, inserted the batteries into the stirrer and threw the magnetic bar in the trash...
After a little chastisement...we laughed a bit about why she would throw something out that looks like that (it doesn't LOOK like trash). Anyway, I'd like to compensate you for the postage, time, and bar if possible. Please let me know a good price and we can work it out.
