I have used it 4 or 5 times and it has worked for me well. I use it to grow yeast in my starters which has worked well for me.

Works as advertised. Functional stir plate for the $$ if you get to brew in your garage or similar where you don't have to listen to it all the time. Mine is on my work desk since I live in an apartment. Was tolerably noisy at first but got very loud after building starters on 2-3 weekends which sort annoys other people in the house. This morning the housing was removed to access the inside pushed and adjusted some stuff for better balance and less vibration; also lubricated the motor shaft. Now it's back to baseline maybe even a little improved. I may try to sell it and pay for a better machine if it keeps requiring as much maintenance.

I was skeptical about purchasing this as I feared it would be too small for the 5L flask and the bar wouldn’t stay in motion. Glad to say it works perfectly and after a year of use! It also works well with my 2L flask. I might get another in the near future.

Bought this looking for something to stir a 5L flask. Does the trick pretty well. Might need a larger stirbar but does pretty well with my smaller one. Great value sturdy powerful and compact.

Was having trouble with a different brand that wouldn't spin the stir bar without assistance. This one works great and the know adjuster for speed let's me choose exactly how much stirring I want. Nice and compact too.

Works Perfect. Excellent Value.

Just received it and I'm giving it 5 stars. Even though package only says 1000ml it stirs my 5L flask perfectly. Works all the way on high for a 1in stir bar but it creates a vortex and stirs everything fine around 1/3 power. Great product and cheaper than most others on the market. Comes with a 1in stir bar and an extra fuse.

I don't know but this plate makes the little bar go whirrrrrrrrr and the yeast starter foam up real good.

Works like a charm. I get GREAT results with my beers.

First time using the magnetic plate. It made making a yeast starter easier. Only problem a very minor one is getting the magnetic stirrer out before pitching. I give it a 5 star and would recommend.

It works great. It works like it’s supposed to handles my 2000ml flask with no problem.

I make starters for all of my beers and this sure does beat trying to remember to shake the flask. Once you find the "sweet spot" I baked it with a line. That spot gives optimum mixing without throwing the stir rod. I also use this with the Propper starter so no more messing with scalding liquid

A little bigger & bulkier than I hoped but it’s quiet and does the job. Overall very satisfied.

Works great - very quiet

The plate held a Erlenmeyer Flask with no problem and work wonderful on my last batch. I really enjoy the light to ensure power is on or off.

Most plates I've found in the past required a larger commitment/investment of money. This is a nice entry point and may be all I'll ever need. (I don't do massive lagers or anything over 10gal) Perfect size for a 2L flask. I'm sure it can handle more but I've never had to turn up the dial even 1/3-way yet. (only used it for 2 FFTs so far my first full starter will be in a couple of weeks)

I needed an upgrade from the stir plate I purchased when I started brewing 1L yeast starters. This plate is definitely strong enough to get my 5L starters in suspension especially with the 2" long stir bar. Nice product. Great price.

Works well. Not the most powerful or fast but effective for 1L yeast starter

New addition to my setup and have only used it once so far but it did a great job of kickstarting my yeast starter.

The stir plate is a good value. I have a 5000L flash and it sits on it comfortably. My complaint is not with the stir plate it is with the included 1" small magnet. The 1" magnet is too small. There is not that much difference in cost for a 2 inch magnet to be included instead of the 1 inch. The motor is strong enough to turn a 2" magnet very well which is what I eventually needed to purchase.

Rugged build. I have only used this stir plate once but it seems more than adequate for the job. The plate is a little small for my 2L Erlenmeyer flask and the stir bar was a little small but both worked well.

I typically use a 2000ml flask for starters. And with the smaller magnetic plate on this and the fact that the exterior edge is raised there is a little gap between bottom plate surface and flask so I often have issues getting the magnet to stay centered or start centered. If it were flat and larger it would be perfect. Get the sense this is designed for smaller flasks or containers that fit down in the raised dish part of the plate.

Works as it should and compact.

Does the job for a great price

I remember when the big online stores sold stir plates for $80. This little number is a great value and does everything you need it to. Nice range of speeds and good build quality. You'd probably spend more money buying all the little electronic parts you need from amazon if making your own.

Love this stir plate which can handle my big lager and strong ale starters up to 5000ml with no problem and doesn't "throw" the stir bar like my other unit. Very easy to start --no fumbling to get the stir bar aligned with the magnet. On//off switch is nice to have and the speed control knob is responsive. Very solidly built and with a nice long cord. The metal platform that houses the magnets might look too small for a 500ml Erlenmeyer but it works just fine for all of mine. Highly recommended and a big upgrade over the project box-based unit I'd been using until now.

One had to use it once so far. The base is just big enough to hold a 2L flask within the indented part.

This stir plate works perfect for my yeast starters. I haven’t had any problems with it yet.

Glad I bought this and for the price you can't really beat it. Works great.

I've used this stir plate twice now with both the included 1" magnet and an optional 2" magnet. With 3L liquid inside a 5L E. flask and the 1" magnet there was no problem adjusting the speed enough to create a nice whirlpool. When i tried the same 3L liquid inside a 5L E. flask and a 2" magnet again had no problem creating the required whirlpool BUT unless the speed is very slowly increased the magnet would be thrown to the edge of the E. flask. In general as the speed dial is adjusted clockwise the magnet speed increases BUT between about 10 o-clock and 11 o-clock position there was little if any speed increase which suggests to me that the internal potentiometer is not 100%. I'll watch that this behavior does not worsen.

Very happy with the stirrer. Quiet strong enough to easily put a vortex in a 1 or 2 liter starter. Can’t believe I screwed around with a diy cigar box now for just about the same $. Rob

it is small but dose the job well
