Greetings All - I have a maelstrom stir plate and I love it. However, my first one started giving me a problem while stirring my 5,000 mL flask; it only pulsed and never spun the stir bar. So I contacted the vendor, Midwest Supplies, and they sent me a new one even though the warranty expired.
Regarding the cheaper stir plates, I had one before I bought my maelstrom. I don?t recall the brand, but I believe I paid about $60 for it. It lasted about 18 months and all the while I struggled getting the stir bar to sit properly over the magnet inside the plate. The magnet kept throwing the stir bar off to the side. Was a real pain in the..... The maelstrom literally sucks the stir bar into exact position and away we go. Yes, it was a little pricy. But worth every penny and Midwest Supplies really took care of me with my purchase.
