Feekoon3000 RPM Magnetic Stir Plate with 5 Stir Bar and 1 Bar Retriever, Magnetic Mixer Stirrer Max Stirring Capacity 3000ml for Lab Brewing (No Heating)

I use this to mix up my preworkout and field of greens. Works well for drink mixes. Make sure to fill the glass with water and turn on the spinning magnet, then add your powder, otherwise it gets stopped up.

It was 5 stars, even went and bought a second one, now we are about 3 to 4 months into owning them, and one is completely dead the other one I have to start spinning it with something else. I don't abuse them, just a couple times a week use them to spin some powdered nutrients to dislove the powder. They sit on a workbench, no kids have access, they were not misused, they just don't stand the test of time. Not even for a little bit.

Performs great

This magnetic stir plate has really helped with my mushroom cultivation. I maintain my own liquid cultures and so when not in refrigeration; they need to be stirred regularly. I have a hot-plate stirrer but it will not get up to sufficient speed to really mix floaters on the culture top down into the culture itself. This little magnetic stirrer, however, easily handles this task and, in fact, I need to watch how far I turn it so as not to fragment the liquid culture and stress it. This product also can run for long periods of time without problem. I have had this running for several weeks solid now, swapping out cultures daily. Great product!

This is just a piece of plastic. It dies not work. Would like a regund and return.

The media could not be loaded. This is my 3rd attempt at "off-brand" magnetic stirrers, and although the others functioned adequately, this one out performs the others. There are no novelties with this stirrer... No 3 random heating levels, no usb power port, just pure functionality!That seems to be the theme to this stirrer. It has these black and red arrows to help center the flask/beaker. The control knob has a noticeable extrusion to help indicate the power applied to the stirring.All of this is great, but the problems I've face is getting over 800mL of solution free spinning and mixing at a rapid pace. I got 3 bars ready to see what is needed to pull the surface down with just distilled water, the medium bar included, the large bar included, and my BEAST bar that would be a failsafe. It only took about 75% power with the medium bar to meet the bar!I'm extremely satisfied with this magnetic stir bar. I'm waiting to put my fume hood together before I pick back up, but I'm genuinely happy with the test performance of this magnetic stirrer!
