Huh, so I only saw it afterwards. There is this tiny rod placed inside the container. I thought at first maybe it could work with a steel ball, but apparently the video show a metal rod inside of some kind.

According to some other website, it is indicated that you also get 20 x metal pins.

Looking at some photo, it sort of looks like each metal pin is about 14-15 mm long, which should fite nicely inside a small Vallejo bottle of paint. 🙂

I'll order this next week. 🙂 At the very least it will be usable for my primer paint and probably also my smaller Vallejo bottles.

please let us know if it works 🙂 if it does work, it seem much better than any shaker 🙂

in their website, they seem to only have information in Chinese... nothing in English dspiae.com/a/PRODUCTS/PRODUCTSD/97.html
size of the pin seems to be 18mm. for what i see in other site, the rods are just steel

i got the feeling that steel ball will not work. since it will stay in the middle of the bottle, while the rod works "almost" like if you have mixer inside of the paint. you only need to buy one for each bottle you have (supermagnete.de/stabmagnete-neodym-rund could help)

i am tempted to make my own.... Youtube Video

not much use for my Humbrol paints lol

Interesting, looks as a technique from labs, let us know your experience 👍

One objection/concern, is the apparent lack of a regulator, it seems to me that maybe this product has one speed only. I guess I should check and see if the product has a regulator for the speed, or not. I guess, if crazy fast then, I guess one would want to maybe limit the time used mixing the paint.

Looking at the vortex pulling in air maybe, looks imo a little weird, maybe not the best for paints I am thinking, but maybe the effect of this is marginal. I vaguely remember someone pointing out in a video that, shaking the bottles upside down, mixes air with the paint, suspecting the mixing method changes the consistency of paint. And it if doesn't do it once, then maybe repeated mixes might, but heh maybe not.

I've seen a review of this product, that tried metal balls. That review suggested that rod vs balls was a draw, but precise placement of the paint bottle on the device was more important to a good mix. Interesting to see how you get on long term.

I was thinking, it is not possible to see inside a Vallejo paint bottle. So, when I get one, I would want to cut a couple of bottles open and fill it with liquid and see how the rods are spinning, given that the bottom of those bottles aren't like smooth glass. Ideally I could try find some more gooey liquid, but I don't know what that could be, or I could perhaps sacrifice some amount of primer paint from one of my large bottles. I wouldn't be able to see the moving piece though with primer paint, but I could at least get a visual on any swirls on the top side, then use water to see how the metal parts actually spins around.

In the website they seem to indicate ("seem" because it is the Chinese version, and you can not use google translate with images....) that you need a flat bottom. Also, it seems obvious that if there is a bump in the bottom, the distance to the magnets increases and it may be less effective. Also the rod may not spin so freely.
In one review the guy complained about how the switch of the dspiae works. I believe there is no speed regulation. either is full power with usb connection, or lower speed with batteries.

It may be possible to use a variable power supply using USB cable. Then you can have different voltages and different settings. But in that case, better build the complete thing, I think.
