Wow! That's a great price if it's a good quality product. And whether you choose to purchase from a vendor on-line or in a local store, quality should be the main consideration. Are you getting what you're paying for? I can't tell you if the products from the vendor you referred to are good or not. But I can tell you that there is a lot of crap for sale out there that doesn't live up to the hype when submitted for laboratory analysis. Allow me to refer you to an informative web site where you can educate yourself on Colloidal Silver
. It's unbiased and they're not selling anything. Go to: http://www.silver-colloids.com/Reports/reports.html?partner=37&gclid=CM-Y5ci-...
Near the bottom of that page is a chart showing the lab analysis of many of the " Colloidal Silver
" products that are being marketed. It's a real eye-opener.
To address the home generator issue: after a lot of researching via the web and elsewhere, I decided to purchase a generator for my home. I chose the Silver Lungs system and yes it is spendy but comparing the cost of the unit versus buying a commercial ionic silver product from "Sovereign Silver" at $50 a pint, the unit paid for itself in about three months and my ionic and Colloidal Silver
product now costs me the price of a gallon of distilled water. The Silver Lungs generator impressed me as a premium quality system that was well thought out and most importantly (in my mind) - SANITARY. It's a closed system with laboratory quality glassware and other hardware so it's easy to keep contaminants out of you silver solutions. The kit contains everything you need (except the water) to get into the production of high quality product and maintain your equipment. It will allow you to make both ionic silver and colloidal silver and comes with a professionally printed manual that will tell you exactly how to make excellent product the very first time if you follow the instructions. I'm very happy with the Silver Lungs system which I've had for about two years. I think I made the right choice and would purchase it again.
