Home made DIY ejucie here
I purchased those bars to stir, as my flat neodim magnets did struggle, no vortex at all no bubbles, as those arrived today, base machine have same configuration, default rpm and I was able to dissolve my menthol crystals in 70/30 VG/Pg within 40 minutes with this. There is vortex also bubbles presented. All you need to find is correct size of stir bar for your ventilator speed and magnet size. In a fact I ordered second batch right now. I would recommend it.

Good quality
The media could not be loaded. Great on-time next day delivery. 6 magnetic bar stirrers. I use a magnetic laboratory stirrer in preparation of food and drink and it can take the tedium out of food/drink preparation. First Class! Apparently to get all nutrients out of tea, it should brew for 6 minutes.

Good length and good quality
I have nothing to compare with, but having used them they're a really good length even for a jar that doesn't have a flat bottom. You have to place the jar carefully on the stirrer, but that's my fault for using non-flat jars. I would buy these again.

Weak magnets
These magnets are incredibly weak and therefore unsuitable for me. They are stirrer magnets, they will work if you only need a weak magnetic force

acid/base resistance my ass
CORROSION RESISTANCE: The stir bar is made of a magnetic core and PTFE shell. It is corrosion resistant and has good chemical inertness. It can be used with most chemicals and solvents. (Such as strong acid, strong alkali, water and organic solvent) used to be good quality not any more had half the pack disolve in ammonia ..... suggest stony labs stuff from now on
