FOUR E'S SCIENTIFICLaboratory Vortex Mixer Various Speed 0-3000rpm, Touch & Continuous Function - Vortex Shaker Mixer Test Tubes Acrylic Paints Ink

I bought this item to mix small paint bottles. It excels in this role. I did ding it for value for the money since the capabilities of this item far exceeds the amount of power needed for my usage. That's really a ding on my laziness, I guess. There should be some unit of measurement to characterize the power of the mixing action. But I didn't see any or find any in my research. I'm happy with the purchase because it does what I want it to do, mix small bottles of paint, exceptionally well. I know nothing about the characteristics of this unit other than what's in the Amazon item description. If you have a question about those parameters, please read the item description.

So I bought this product immediately after returning a vortex mixer from LabGenius, and that one did not work out of the box. I was looking for something to mix my glue for my eyelash extension adhesive to get better retention for my clients.Shipping was super speedy - I received the product literally within one day of ordering.The product itself is fantastic! It's simple enough where you can just plug it in, and there's three different options to turn it on, off, or a mode to touch and it'll start mixing. For my purpose, I have it on the touch mode so when I need to mix my glue during sessions I just hold down on it and it'll start mixing. There are different speeds and you adjust the knob to pick your speed. For my purpose, it's perfect and is a good enough mixer to mix the adhesive. Also the suction cups work really well so far! Highly recommend this seller!

I have been using this to shake my Createx air brush paint bottles. Does a great job at mixing up the paint.

**UPDATE**4E contacted me after my review and offered to send a second mixer out, which they did. The new one is, if anything, more powerful than the original - this one shakes the little table I have it on when it's running full tilt so hard everything begins to vibrate off it. I have to turn it down, which may be an indicator the original was faulty to begin with. I haven't used this one quite as regularly, but I've tried to use it a bit each week since getting it, and it so far is running like a champ. If this changes, I'll edit this again, but so far it looks like I just got a bad unit to begin with, and this one is better. Further updates if things change, but otherwise I'll leave it here.**Original Review**Got this product for mixing model paints. Worked fine for the first month, used it on the touch setting for maybe five minutes at a time, once or twice a week. It revived several metallic paints that were dying great. Went to use it this morning and when I turned it on to either touch or continuous, the platform weakly shifts a little and then nothing. I've run this thing for less than an hour total for the month I've owned it, and it's already dead. I've unplugged and re-plugged it, same issue. Do not recommend.

This mixer is big and powerful. It's sturdy and feels well made with no cheap components that I can see or feel. I have the smaller vortex lab mixer already from Four E's and it's also great. So, when I saw they had a new larger version with different mixing heads I was interested in using it for my primers at my airbrush station. This mixer will work best on a sturdy surface/table/floor. It's a beast.As you can see in the photos, the worst of the worst separation was quickly "vortexed" into a creamy smooth liquid blend again. I don't even bother adding the little steel mixing balls to the big bottles, but they'll probably be helpful with smaller pots and your more oddly shaped bottles.This brand of primer, aside from separating so badly, is otherwise excellent (although ridiculously named), and I was sick and tired of feeling like I needed shoulder surgery after shaking these bottles by hand.If you already have a smaller vortex mixer for the little paint bottles and could use a hand with your larger bottles, then you can't go wrong here. The mixer also comes with a smaller head that fits your standard size miniature paint bottle, but it feels like the size and power would be overkill if that were all you planned to use it for. If you mostly need to shake the little bottles and don't have any mixer currently, then the smaller size Four E's vortex is the best bang for your buck.If you've been looking for a solution that can handle any size miniature paint bottle on the market (haven't tested a rattle can yet...🤔) then you'll be happy with this mixer.

You could buy a vortexer on a scientific website for double or triple the price OR you could buy this one and it works just as well. I have been using it for months and have had no issues. I typically use 15mL falcon tubes on it and it is good at vortexing.

2 months and it's working fine. I use it for a lot of things. Mixing vape juice, shaking up old pens, primarily though I bought this to mix my old hobby paint from years past. The money you spend on this product will pay for itself eventually. It's not a miracle worker and won't revive dead paint without some effort on your part to mix it correctly, but it's certainly better than hand shaking hundreds of bottles of paint when you just want to get back into painting again.

I paint miniatures for ttrpgs and wargaming. This means I have, oh, 400+ little bottles of paint to shake... I know this mixer seems a little overkill but believe me it is worth it!I paint with mainly Reaper paints and this makes VERY short work of shaking those bottles. I also use thicker paints from Citadel and Army Painter and this also does a fantastic job, although it takes a bit longer as they’re VERY thick paints compared to Reaper. All the aforementioned bottles and pots fit inside the little black shaker attachment without issue. I use the touch function and it’s a very nice feature of this mixer. Operation is not completely silent, but not offensively loud. It’s a low hum at best... I am extremely happy with this machine and now I can’t live without it for my hobby.
