Better to use magnetic stirrer with Utopia generator?

Hello! I bought a Utopia-Silver generator based off what I read here. Is it true that this generator is slghtly better than other generators in terms of colloidal content?

I see that this generator doesn't alternate the polarity on the elctrodes, would it be beneficial to get a magnetic stirrer to use with this generator?

Why are the other generators like the silvergen so much more expensive than the utopia generator? Just the features? Things like auto shutoff don't bother me, I can just turn it off myself.

Also, I'm thinking to sell this generator to get one that also does Colloidal Gold and other metals if I like their effect if I can find one that isn't too expensive or build one easily.

So right now, I'm just curious if it would benefit me to get a magnetic stirrer to use with this utopia generator?
