FOUR E'S SCIENTIFIC Mini Vortex Mixer - Lab Vortex Shaker with Extra Silicone Cap & 300 pcs 7/32 in Mixing Balls, 5600 RPM, for Acrylic Miniature Hobby Model Paints, Green

This vortex mixer has been very effective for the use that I got it for: quick, thorough mixing of small pots of liquid or semi-liquid paints. Specifically, Reaper MSP paints, Vallejo GameColor Inks, GreenStuffWorld Fluor paints, Secret Weapon, Army Painter, MIG, AK Interactive, Games Workshop contrast paints, and generally all types of thin washes and inks all mixed very well. The only caveat was around thicker paints: outliers like Vallejo Model Color dropper bottles and Games Workshop metallics pots (e.g. Leadbelcher) were too viscous to effectively mix.The device is heavy enough and the three-leg design with rubber feet is stable enough to prevent motion or drift while running the mixer on a desk surface. Sound while running is audible not but not loud.Quality assurance: my mini vortex mixer died after just over 11 months, with an internal mechanical fault that caused it to stop rotating/agitating despite electrical power still working and the top sensor switch still functioning. To their credit, 4E's Scientific did provide good support. They were communicative when the problem was reported through Amazon, and did quickly provide a within-warranty replacement after being provided with video of the fault.I would give this a guarded 5/5 rating due to the effective use of it with (nearly all) of the miniature paints I use it with and the warranty service that 4E's lived up to. If the warranty replacement mixer ends up breaking down the ranking would go down, but this is an excellent mixer while it runs properly.====Update 2022-07-12: the replacement mixer is still going strong after one year, so I would now give this an unreserved 5/5.====Update 2024-02-09: the replacement mixer is still going fine after 2.5 years, so definitely an unreserved 5/5.

This is a laboratory grade mixer but works quite well for mixing small bottles of paint used by hobbyist. It is heavy and stays put while in use and creates an vigorous mixing action.

I had my Mini Vortex Mixer for almost a year when I had a connection problem with the power supply where it connected to the mixer. Their customer service provided me with a new power supply and I only had to pay for shipping. I am a miniature model painter and I love this mixer and it is very effective not only with miniature paint lines but also works great with hobby style paints like Apple Barrel and other brands.

Does a quick job of mixing paint. The base is heavy enough to ensure no movement when in use.

Had a smaller one and returned it. Bought this one and have 0 regrets! Yeah it's a little more money but this things an absolute beast on Createx, Liquid Kicks and even Angelus. It's powerful and fast! Seems pretty stout too! Don't mess around with the little cheap ones. Get this and call it a day

Good quality, good product

This does and amazing job mixing model paints.

I have only just received this product and tried it out on a few hard to mix paints. It does a great job and takes a lot less time to mix the paint than trying to shake them or pull off the dropper nozzles to stir them with a metal stirrer. The unit is very well built. It is solid plastic with good rubber feet, and the switch operates easily when you push down on it. While mixing it is very quite and doesn't vibrate excessively or move around on my desk. It only takes a few seconds to mix most paints, and stubborn ones only take 30 seconds or so. It is easy to use with the bottles upside down as well, and larger bottles work just as well.

Don't waste your money on cheap black mixers....they don't last long. This is a beauty....well made and performs great.

My son showed me this, but didn't want me to spend so much for his Christmas gift. I looked at the reviews of the cheaper one and this one. By far, this one seemed the best choice.I surprised him and explained why I decided to buy it.He said it worked great!

Don't hesitate to purchase this unit

Used on paint that had sat for far too long. did a marvelous job. Nice and stable and strong effect. Use with an agitator (Stainless steel ball bearing) for acrylic paints. Do not use on inks (oops), takes them a while to settle.

Fast and easy just load and shake my airbrush paints back to life Just that quick.
