I bought the Taylor SpeedStir earlier this year, and it's been really handy for testing. I've been happy with it.
But... (of course there's a "but") lately, the bar hasn't really been spinning in the cylinder. Instead, it sort of vibrates, and makes about 10 revolutions per minute, compared to the high speed it had when it was new. It still mixes, but not nearly as quickly as when it was new. I'm using the mixing vial that came with it, and the vial is clean. I don't see any damage that could account for this.
Has anyone else experienced this? Is it simply time to buy a new bar?
Has anyone opened one up to determine how it works? Does it have a motor that physically spins a magnet, or does it alternate the fields through a coil to "spin" the field itself?
