Hopefully whoever reads this review will get the opportunity to buy this mixer at or around the price i paid for it because it was a fraction of the cost of other mixers produced from lower quality brand names. I'm using mine for mixing tattoo inks and let me tell you what.... this little mixer has saved my triceps from having to do all the work of mixing up ink, i used to shake ink until my arm was burning and fatigued, but i just had to work through it, well not anymore thanks to this little guy. This is the second mixer I've purchased, the first one was a generic mixer that ran at 1000rpms and I'm way happier with the 3000rpms of this machine. Ink seems to mix more efficiently, be it the lower RPM's or different brands I'm not sure, but you can remove the silicone top cover and the little plastic cap thats in the cover where I decieded to use a very small but strong flat and round neodymium magnet that I assume helps move the ball bearings used in ink bottles. (Yes I know not all of the steel balls added to ink bottles are ferrous, but the ones I add to my grey-wash are) It doesnt seem to affect the machines performance seeing as how its very light... But I'm not gonna mention that to Vevor lol
