Great Stir Plate!
Excellent stir plate at a reasonable price. Nice large surface. Have made two starters so far....and this thing really does the job. I use a 2 liter flask to make about a 1.5 liter starter from harvested yeast.
First starter with this stir plate.

It’s ok.
It’s an ok stir plate. I didn’t have time to build one myself so I bought this. I love the timer. The controls and the build is kind of cheesy. Don’t drop this from more than an inch or it will be in pieces. Just be aware it’s not industrial or even school grade. Still happy I bought it.

This thing is GREAT
I recently stepped up to a 15 gallon system. It was obvious that i needed to step up my yeast production. I took a "chance" on this yeast stir system.

It's a little noisy, but HOLY COW (thanks to Harry Carey) does this thing work.

Don't fool around with others, save up and buy his one. Hands down, the name says it all, GREAT YEAST STIRRER.

needs more info in byline.
Not experienced at making beer, but trying. So I ran across some info about a stir plate for help with yeast. When it arrived I read instructions and it is designed for liquid yeast not dry yeast. Since I have never used liquid I now have an item I do not need at this point. It would be nice if this info was listed below the picture.

Best stirrer made!! Period!
This thing is the bomb! After reading a lot of bad reviews I had gotten a bad image of this stirrer. After deciding to take the chance I have to say that I could not be happier. My 5000 ml. Erlenmeyer flask fits with room to spare. The gradual speed change is a great feature, as well as the pause button. The timer also makes it nice for long starts. Way powerful as well. Worth it!

Easy self explanatory right out of the box
Excellent product. It is a must have glad I made the investment. Hope it lasts a long time.

Oh Yeah!
This thing kicks butt (instead of kicking the stir bar) with carboy sized starters. Easily centers the bar through the thick glass of carboy base. I also like the fact that the surface is pretty much waterproof (not for submersion) and spills / splashes /drooling are easily cleaned off.

What is the most sanitary way to get the magnet out of the yeast before pitching?
S C on Jan 29, 2016
BEST ANSWER: I pitch yeast starter through a sanitized funnel with mesh filter that captures the stir magnet so it doesn't enter fermentation vessel.
