Mine does not work. Can someone help me ?

I bought this mixer as a way to mix bottles of acrylic paint, primarily for painting models. It works awesome. I would definitely recommend it for this. My only caveat is that I've had it about a week, so I hope it holds up a long time. I'll try to update this in a few months to state how it is. If you don't hear from me, it probably is still working.

I purchased this mixer to use for my hobby paints. It worked well out of the box for a few months and worked pretty good. After not using it for a few months I got it set up to use it again and it didn't work anymore.

The first version was DOE but Amazon sent me a replacement. This wasn't my first choice or second even. My first choice was out of stock and the second choice got lost in the mail. I bought this for model paints. Specifically, G Paints I got from overseas. They are lacquer paints and had a lot of settling. This worked to mix them really well.There are a few things of note. It will take time to mix the paints depending on how bad they are. A new paint pot that you use pretty regularly is probably going to be perfect in 30 to 60 seconds. Something that has started to show settling? You are looking at 3 to 5 minutes. Really bad separation? 5 to 15 minutes (or more). You will know when it's done.You may need to rest your hand. You do have to actually hold it and it does mix pretty forcefully. Having an agitator (glass or steel ball) in the paint pot will help as well. You will need to change the position of the bottle from time to time to mix everything.I saw people complaining that other brands had a sweet spot that you needed to find to get it turned on. This was activated pretty effortlessly. Just push the put on the center. It doesn't have to go in the hole used by test tubes but should cover it. The top can go into that hole.One other tip I have is to shake the bottle when you plan to switch positions. I start with the bottom touching the mixer and when I go to flip it over or lean it I will give the bottle a simple shake. A lot of times this shows me what is still settled.In closing, I have to give this 4 stars. Half for the DOE model and the other half for the cable included with the mixer. It's short. Like maybe 16". I would have liked one that was 2 to 3 feet.

I ordered this mixer to use for paint mixing for airbrushing. It's a bit pricey compared to some options, but it's a lot more sturdy, it's quieter (especially on a foam base), and it comes in handy for when I need to mix items in centrifuge tubes (good ol' work from home). For use with paint, highly recommended. I use the 17ml dropper bottles, primarily, and this works terrific. I usually just hold the bottles on the mixer top down, sometimes bottom down. Both work well. I've also mixed other (small) bottles of paint by holding them on their sides, top, bottom, whatever. As long as you have a good grip on it, you can mix it. Sometimes it works well to push down with the pad at the base of the fingers while holding the mixer with 3 fingers, trapping the bottle. It doesn't take long to find a good method of using the mixer!As for the vendor, the unit is packaged professionally and well protected in transit, looks great, etc. but where they really shine is customer service! I had an issue where my daughter damaged the silicone cover shortly after I bought it; I messaged the vendor asking if I could purchase a replacement cover and they simply took care of it for me. Very fast response time, very fast shipping. Greatly appreciated, highly recommended!Also, silly putty is made with silicone oil, so don't get silly putty on your mixer or it will stick fast and make the worst kind of mess!
