Lab Vortex Paint Mixer 100-3000rpm Vortex Shaker with LCD Display, Touch & Continuous Function Orbital Diameter 4.5mm Acrylic Paints Nail Polish

So far, no complaints. I bought this to mix old modeling paints, which had been sitting for three years. For single bottles, it works perfectly out of the box. It will take some customization if you want to use the foam insert to mix up to nine at a time, but it can be done.

We got this mixer to use with gel nail polish bottles, and so far it's working great. The polish is blended nicely, set up was easy, straight out of the box and plug it in.

This is a nicely built vortex mixer that is similar to the kind I've used in a lab, with a nice big display and an easy touch function. The feet are adhesive and stick well, though it will shake the whole counter if it's not secure like a lab bench. One reviewer mentioned suction feet, which I think might be because he did not take off the stickers. He might have also received a slightly different version than mine. The continuous mode is poorly documented. I was hoping to set a low RPM speed for gentle overnight runs, but it shuts off after around 1.5 hours even if I set the time to zero. The manual, which is a bit in Engrish territory, is vague and says continuous mode works for a "very long time." Also, this mode aborts early at max RPMs, which I think can happen when it never really gets up to speed and it just gives up. This is preferable to overheating and damaging the motor, but I wish it gave some indication if that is the reason. The little top shelf for continuous mode is also a little confusing. It has a rubber top, which can't be used with a thumb screw to hold it in place since the thumb screw only works with the foam test tube holder. That tube holder started to spin on me without the rubber to prevent that, so I just did not use the thumb screw. I ended up 3D printing a holder for my bottles of shellac based stain. Despite my critiques, the mixer is quiet and does a great job mixing stubborn gelatinized shellac. I am happy with it overall.

Pros: Wide speed range of 100-3000rpm Powerful motor Large LCD display shows speed and time Touch and continuous function Built-in timer Easy to clean Cons: Mixer can be a bit noisy The mixing cup is made of plastic, so it may not be suitable for all applications The rubber is wearing down over time

I got this vortexer for mixing paints and settled fountain pen inks and so far it had worked out well. Much faster and less tiring than shaking them by hand for sure. The base is nice and heavy so it doesn't move around too much during use, but the suction cups are a bit weak so it does move around a little. It comes with a few attachments for larger-base items and for holding multiple test tubes if you're in a lab. Thanks!

This is very nice, it has a slight learning curve but once you have that down it's excellent. We are very happy with the quality and performance of this. This deserves all 5 stars and then some.

I like that the LCD and its aspects show speed and time. I like that it is multifunctional as well. All I expected from a vortex was met. I am Pleased!

This vortex 4.5mm orbital mixer with LCD display from LACHOI is a high quality and well made mixer that offers speeds between 100-3000rpm and has a large LED display with a dial to set your desired speed, this mixer commonly used for lab work, nail polish and paint mixing. the mixer works very well but they is one thing that is very annoying and that is the suction cups in the base of the mixer, i can't get them to stick and i tried on a few surfaces. i have a few more mixers that stick just fine but i have to hold this one every time i use it. i basically use this mixer for my airbrush projects to mix paints mostly lacquer based, i do get very good results every time i use it.
