Magnetic Stirrer Set(4 Stir Bars & a Retriever), Strong Magnetic Stir Plate 3000rpm with Speed Control for Liquid Mixing, Magnetic Mixer for Chemistry, Lab, Yeast Starter, Drinks & DIYs

Ordering my second and third unit now. This is the coolest thing ever. It’s a great value for your money. Very low noise level. It’s easy to use, just plug it in to an electrical outlet (it is not powered by USB and it does not have a battery). Drop in one of the four provided spinners in to your cup and place your cup on this device. Rotate the knob clockwise past the initial click to turn it on low. Continue to turn the knob clockwise to increase the speed. When you are done, use the provided rod to fish out the spinner, as they are magnetized making it easy. The quality seems good so far, I’ve just used it a few times since getting it yesterday. But I’ll be using this one (and the others that I’m buying once I submit this review) extensively on a daily basis to mix my batches of perfume. I tried it out using a smaller glass jar with my perfume in it and it works great, as seen in my video. I also tried it out with a 200 mL thick glass cylinder and it worked just as well.

I use a chemical test kit for testing pH, chlorine, total alkalinity (TA), calcium hardness (CH), etc. for my pool, The kit involves adding drops of chemicals to a water sample some of the chemicals used to test TA and CH do not always mix well when a drop is added to a water sample and in some cases 20 to 30 drops of chemical may be required, with frequent swirling. Doing the tests manually swirling the water is both tedious and times taking. The Ayinlab Magnetic Stirrer Set works great to continuously stir the water sample well drops are added for TA and CH. The hard to mix chemicals mix immediately, and there is no need to pause while adding drops to manually stir the water sample. The kit nicely speeds the testing process while removing some of the tedium of the testing steps. Very happy with this product!

Nice unit , quite..and comes with some good accessories

This was an absolute game changer for me. I make oils and wax melts and normally have to take 2-5 minutes and stir manually. Having the stirrer frees up that time for me to be doing something else. Love this thing. Total game changer

This little stirrer is really great. I've only had it a day so I can't speak to it's longevity, but it seems really solid and was ready to go out of the box. It made a huge difference in mixing my son's supplement powder. I tried it water flavor powder as well, and it ends grittiness. Totally worth it

Love this item...use it for film developing chemicals and works great...love the different size magnets too...quality is top notch and easy to store...

I bought this for re-hydrating yeast, and mixing yeast nutrient for home brewing. First thing I did was play around with it. It's light weight and portable, sturdy when place on a surface and its variable speeds make it useful for all my needs.

Great product that works very well
