The stir bar that arrived works well. It is flat on the sides, does not have a ring in the center, and it is quiet. I ordered the keeper magnet with my stir bar, but it did not arrive with my package. I've always had great order accuracy and customer service with AIH, so I chalked it up to "something was bound to happen sometime," and grabbed a magnet off of the fridge. I would give the stir bar a 4* rating, but the package of stir bar and keeper magnet that is missing a keeper magnet a 3*. AIH Note: Please contact us if you are missing any items in your order. We can either send the missing item(s) or issue a credit. Thank you!
