Features:
1.Quantity: 7 PCS stir bars of different sizes and shapes + 1 PC recycling rod
2.Material: PTFE (Polytetrafluoroethylene)
3. Magnetic retrieverSize: 10'' ( 10mm in Diameter * 250mm in length)
4. High temperature: the use of operating temperature up to 250℃
5. Corrosion resistance: for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents
6. High lubrication: the lowest coefficient of friction in solid materials
7. Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196℃, can also maintain a 5% elongation
8. No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance
9. Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged, there is B06B plastic in the best aging life
10. Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions

The cross and gear shaped ones are two big to fit into flasks (24x40). The other ones are fine. The retriever rod is helpful.

When using the capsule shaped stirrers, there was no problem. Only one was "off center" But using the cross shaped stirrer along with the multi point one, they both rotated off center. Though the worked fine at low speeds, but at higher speeds, they flew out of "orbit" causing all sorts of havoc with the liquid and the container. After returning and ordering other sets, I did find one that all the stirrers stay centered.

works as expected for the money

So I use a small, rated for 500mL (water) magnetic mixer for mixing PG/VG. The pill that came with the mixer is poorly balanced and even in water, will not support going over 50% speed.The pointy ellipse, starbust, and 2 pill shapes with raised center bars, in that same mixer, were able to pull down a vortex (which will knock them off balance) in a 3500mL rice pot (wider than it is tall) and in a 3000mL beaker. Even in a 1 quart ziploc container (uneven on the bottom because of the imprinted branding) they were still incredibly stable. The magnets in them are much stronger than I expected for such a good deal.In heavier fluids like VG (warmed up to help viscosity) I was actually able to fully blend 1200mL in a 1500mL beaker in one go. Previously I had to do multiple 5+min sessions with hot water baths in-between.The two round bars (smooth pills), cross shape, and kite shape were not as stable / balanced as the other shapes. The cross would be best for moving volume (the starburst is a bit too much surface area for fluids this thick and if the magnet was any stronger it would simply unbalance the mixer's magnet) so that was unfortunate. But for the price, this was surprisingly good quality.When I get a heavier-duty mixer with a harder to unbalance magnet, I'm sure these will probably all perform even better. The poor tolerances of my 5 year old $10 chinesium mixer is a hard test to beat.

These work just as well as similar products from scientific equipment vendors at a fraction of the cost. Would buy again.

These stirrers don't react properly to the magnetic stirring mechanism in my hot plate at all. They act like they're unbalanced which I'm guessing is from misplacement of the magnets inside these stir bars. It's definitely not my hot plate because my other stir bars function just fine.
