4th UPDATE 12/19/15
After 5 years I've only had one mild cold and CS has successfully prevented flu symptoms and other illnesses from taking hold. I ride a bike in 40 degree weather sometimes! I now use the machine sold at SilverEdge dot com by Steve Barswick that has superior quality CS.
3rd UPDATE *3/1/2015*
Many commenters doubt my claim CS can be damaged during the creation phase. I found this visitor's comment confirmed my claim best as follows:
"Silver ions are unstable. And so the moment something is introduced into the solution, the ions will either bind or reduce with the added ingredients. Not to mention, loose their potential in the process."
2nd UPDATE *8/31/14*
This particular generator is good but there's a better and more expensive one people may want to consider. I'd recommend this other micro particle CS generator from The Silver Edge (link below) because it has .0008 microns (independent lab certification) that makes it a more sophisticated to the human body where the amount of PPM isn't the main issue that the micro size of the particles makes the difference for easy absorption into the body. For instance, the unit in this video has a lowest particle size setting of 1.5ma.

http://shop.toolsforhealing.com/RSG_3_Silver_Maker_p/sr-rsg3.htmOne other important bit of information I've learned since this video's release is that that using the nasal spray form of home made CS can cause complications in one's nostrils, particularly dryness of the inner hair follicles that can once again cause congestion. I lost nearly all use of my right nostril due to dryness and another condition my nose doctor brought to my attention. Nose doctor's don't recommend CS nasal spray from home made kits.
Since this video I've only had one cold that last just a couple of days and haven't had any bronchitis that used to knock me out for 4-6 weeks at a time and ruin my gut bacteria due to the antibiotics the doctor prescribed.
If one must purchase CS, the product Sovereign Silver's the best seller on the market and even Natural News recommends it.
A few updates to numerous questions I receive in the comments are as follows:
1. The coffee filter is for removing the silver particle debris from the solution that is dangerous to the human body. The laser pointer system doesn't work well in my opinion.
2. You can contaminate the solution during the home making process, it's not potent when being made. People keep saying it can't be contaminated and I disagree. People are far too casual making this stuff, there's a reason it's expensive on the market.
3. I know this is a poor man
