This is a good generator. In Russia the power plugs and sockets are different. You need a voltage converter and power plug adapter to be able to use this silver ionizer here, in the US. It can be purchased at any store, including Amazon.

Mixed feelings about this device. It has some pluses and some negatives. Should you buy it? Have a look at my lists and decide for yourself.Pluses:- Fast shipping and seller is quick to respond.- Device is self-contained. Easy to use.- According to design it will consistently produce a very low ppm solution (35mcg/L), or a 10ppm "concentrate" (10mg/L), depending on the mode you choose.- Comes with basic operating instructions in English. Not really sufficient to understand its full method of operation, but enough to press the buttons and get started.- Comes with a very well written 60 page book outlining the uses of colloidal/ionic silver with many case studies. Unfortunately it is all written in Russian. I used the Google Translate app in image mode to read most of it. Very well done.- Easy to clean the silver electrode with supplied pipe cleaner.Negatives:- Cannot use 0ppm distilled water, the standard for creating any ionic solution. The device electrodes do some kind of water detection and will not operate in less than a 10ppm starting solution. This is bad, and additional water mineral contents will negatively bind and react with silver. I was told to use tap water. Anyone with experience in this area will find this suggestion to be very unscientific.- For North American use it requires a 110V AC to 12V DC adapter at 100ma or more, with center positive terminal (standard). The included adapter is 220V only. Not a big deal if you have an extra 12v adapter laying around.- Only one silver electrode.- Does not do electrode polarity switching. Since there's only one silver electrode, this doesn't matter much.- Max 10ppm "concentrate" mode does not offer the ability to create denser solutions.- No stirring.- Silver particle size is not very small, as expected for a 12V circuit at 100ma. This is a compromise between speed of operation and quality of end product.One way to avoid the impurity problem via tap water is to add drops of pure ionic or colloidal silver into a liter of distilled water, just enough to get the machine to operate (to detect at least 10ppm dissolved solids). Once your first batch of silver water is done, fill up a dropper bottle and add 20 or so drops to every starting liter, it will speed things up and the quality will be stable.Overall, I think the manufacturer has designed a good product that does away with all the complications of using such a device. Pick up a 12V DC adapter with 2.1mm tip and you're good to go. Four stars overall, a recommended buy for convenience or for non-technical people who just want quick benefits.For creating true colloids from ionic solutions, see cgcsforum.com for tried and true details.
