Thanks for the tip, mine should be here next week.

I bought a used one on Ebay for under 10 dollars shipped. Unfortunately, it seems like it is now dying on me. I am debating on getting another one or trying an ultrasonic cleaner.
Now that I have both. I will stand up and say that the magnetic mixer is much faster in steep time but not worlds different. If you get an usc get one that allows for the water to heat and one that does not have a 3 minute shut off cycle or itâll drive u nuts constantly having to pay attention to pressing the button again. As for the aerating of the juice the mag mixer wins. Usc is good at steeping/ shaking via the ultrasonic waves but you still need to vent your batches and give them some air time.

Is something like this worth it?
Thinking of pulling the trigger this payday!
It looks good to me - Perhaps you should invest in some form of thermometer to make sure it doesnât heat too much? Iâve been tempted ever since I first saw one 
hehe

Before you pull the trigger you may want to look at the DIY Magnetic Mixers firstâŚ

I have looked at some DIY solution just scared I will mess it up

Hmmm, just hate to see you spend over a $100 for something you probably wonât continue to use. It is just so much easier to blend by weight in the same bottles you plan on using. A magnetic mixer will require a flat bottom bottle or a beaker to work correctly. Get a beaker involved and you have added another step or two to your process plus cleaning the bottle/beaker afterward. I built a magnetic mixer and it came out nice. Never use it though. Just really think about it before you pull the triggerâŚ

I know a lot of people swear by them, but I didnât see the convenience in it. I can froth a mix in 30 sec at 3000 rpms. I think thatâs mixed well enough. I usually make 15 to 120 ml batches, between my test mixes and my advs. I can do a 2hr hot ultrasonic bath with up a dozen bottles a once. Can you imagine trying to mag stir all those separately for the length of time some let those run. It would take a couple days if not more.

True that! Also, the mag stir better not have a auto shutoff or youâll be hitting the button constantlyâŚ

I have to say if you were doing large batches totally worth getting one but I got a junker for 15$ it works like a charm for my batches. But if I do multiple small batches which is my style anyhow I just use a frother and crock pot them for a few hours. Havenât even used the ultrasonic in months.
Beakers must be flat bottomed

I bought several 10 ml flat bottomed flasks that are Erlenmeyer style and do a smaller magnet in all of those.
also have larger magnets for 25 50 100 and 250 flat bottom flasks. but the mag mixer doesnât like vg heavy mixes to get around that you need to warm up your vg prior to getting you mixing set up so itâs warm when you pour it and then immediately spin it.

This is one benefit that Magnetic stirrers doesnât offer.
I use 3 of these 5 steps and I swear by the end results after 2-3hr heated USB.
Gas bubbles can be seen streaking through the mix during the USB process.
Evaporation and degasification simply wont happen with the lid on (Think bottle of lemonade)
a) Shaking the bottle (Helps)
b) Stirring (Helps)
c) Whisking (Very effective)
d) Blending to a foam (Super Effective)
e) Ultrasonic degasification (Super Effective)

Well I donât know if you noticed but that magnetic mixer i linked also has a heating plate so it would also heat the juice I donât know if that makes a difference.

Heating does help. I think the frothing and ultrasonic cleaner vibration really bombard the mix at a molecular level.
Check this video of eliquid in a USC.

Thatâs cool! 
I should get one - Not sure where Iâd put it though

So you think something like this
would be more effective? what kind of bottles do you use to make sure that you donât get water in your juice?

Thatâs a high end model. Iâm sure it will work like a charm. I have a smaller 1.7 liter jewelry cleaner model and I can fit 12x 30ml glass boston rounds at once.
Well I think you guys have talked me into the ultrasonic instead of the magnetic mixer with a heating plate. Have you guys tried putting plastic bottles into the ultrasonic. I currently have glass bottles but I have been making juices for some of my friends and as much as I ask for the glass bottles back they donât always come so I was planning on getting some plastic bottles and keeping the glass for myself.
Think i changed my mind on the ultrasonic to get
This one has digital temperature control and is cheaper!

Keep the temp low, and plastic will be fine

When I was researching USCs I ran into a few post that said plastic bottles absorbs some of vibration from the USC. I canât personally verify it to be the case. Thatâs one of reasons I use all glass bottles. Before I converted to all glass I used glass flasks and beakers. Then I decanted to plastic for steeping.
