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

Exactly what I needed for my small lab. It’s plug-and-play and handles 2-liter flasks without any struggle. The motor is whisper-quiet, and the magnetic connection is very strong—no issues with the bar "jumping" out of place at high speeds. Great value for the price!

Only had a few days but it works great. The control is a little finicky but no issue with stir bars being jumpy (at least good ones). Has the ability to go slow and fast. And the stir bar retrieval magnet works great.

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

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!

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.

Does as advertised

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

Garbage. Speed is horrible and does not stir effectively.
