I'd sure promote it for you. I use a heated version and wouldn't be without the heater, personally. Resist the urge to over-speed the magnet as it will cavitate air into the mixture. Just keeping things in motion is sufficient. With heavier loaded powder like Na2SO4, it could require a little manipulating of your mix container around the spin point of the magnet to get the corner material moving but a bit of patience helps (and it sure beats hand mixing!).
