I just bought one and it arrived a couple of hours ago. It appears to be very well built, it's nicely packaged and was shipped without delay. It includes a 'keeper' magnet to hold the stir bar in place when pitching the yeast, and very good instructions. Mine is now happily whirling away in the basement stirring up a starter in a 2 liter flask. I highly recommend this. It's not made to get wet or be used in high heat situations, but these constraints shouldn't be a problem for homebrewers. The price is very reasonable.
