The best thing is, I didn't invest a dime on those shakers, they came from a friend who worked at a lab, they decommissioned stuff on a regular basis. These are the real thing, heavy duty, weigh 40+ pounds. They live on the floor or they'll shake the whole house.Wow you’ve really invested! My Maelstrom stir plate seems to be on the fritz. Kind of a bummer for $150
Sorry to hear about your Maelstrom, for that price they should last a lifetime. What's wrong with it? Perhaps take it up with the manufacturer?
