Which generator: Puppy, Silvonic, Colloid Master, Silver Bullet

I have some questions about the different EIS “CS” generators that I have narrowed down for purchase.

I like the simplicity of the Silvonic & Silver Puppy.

Q:
- They look and seem to behave almost identically – differences?
- - - - The lifetime warr. on the Silvonic is nice! :)
- What is actual production time on the default 16oz pint?
- How long if I do a quart, a gallon..?
- - - - Will mechanical stirring speed things along noticeably?

IE. I'm concerned about production time so I have enough; to put in my dog's water (or even straight for a time), to use in: laundry/cleaners, skin/hair; for my wife, as well as an ongoing hard to kill C. Diff infection I'm dealing with.
FYI: I'm using Utopia-Silver Advanced Colloidal Silver and have gone up to 8oz in a day, and really need to use more than what I'm using daily, 6oz, can't keep that up either, just can't afford to continue with that much daily, let alone more. So I need to supplement what I have left with a generator.

Neither one of these seem well suited for a gallon, or even a quart, but they "say" they can make it. If so..
Q:
- How long does it take, experiences?
- Elixa (Silvonic) had a “Turbo” model that did a gallon, that was cool! But they no longer offer it, any idea why?

So I went looking at the Silvergen... forget that! I can't afford it right now. Bad reviews on the company anyway.
Then I looked at the SilverBullet by Utopia, totally too manual and futzy for me right now, I'm too sick to monkey with that. :/
Their unit does intrigue me though: with its 30% particle to 70% ionic content, but there is limited info on it.
Q:
- Says it needs longer/repeated cook times to get that 30% particle content, isn't that true with any of these EIS home generators, so thereby does that not make it any different at its most basic design level?
- It's the same name as "Silver Bullet Enterprises", it's not the same I assume?
- Does anyone have more info on use of operation and stability of end solution than what I have found here through searching and in its limited instructions, which isn't much either way?


Then there's the Colloid Master, priced nicely @ $134 right now. They quote the same high particle ratio as Utopia's, but it's way more “polished” in its use.. sort of.

Any comments on the following..?

Colloid Master
Positives, compared to the aforementioned units:
#1. Cheaper than Puppy or Silvonic
#2. Makes more, faster than either as well.
- - - - I have read it can do a gallon in 12hrs?
- - - - - Won't this be larger particle size?
#3. Higher colloid (non-ionic) content.
- - - - Is it really?

Negatives & Red Flags (no order)
#1. They have a cheaper unit that's not as robust.. huh.. really???!!
#2. They use .999 'flat' electrodes, instead of rods. (faster wear says Puppy - true/false?)
- - - - They seem to think .9999 (4 nines) isn't necessary... it's just extra copper in the (3 nines) they say.
- - - - Well, what other impurities?
- - - - .9999 = 10x purer & 10x less impurities than .999. No?
#3. I found some bad press on it in the old Silver-List.
#4. It has been said here that it makes “wine” without a stirrer?
#5. It isn't light stable, has to be stored in the dark. (Not very small ionic/colloid content?)
#6. Hokey “electrode holder”
#7. It has a noticeably audible relay that “clicks” as it reverse. UGH!

PS. Sorry if I have intermixed some terms, my health isn't good, my brain is suffering. ;)

I hope this isn't too long, thanks for your help.
God Bless! :)
