The problem with silver retailers is that you don't know what is in their products and the only thing you have to go on is what they tell you it is and there is no practical way to know if what they are saying is correct or not. Consequently, like many others I make my own with a high quality generator so I know exactly what went in it and what the finished product is.
The second issue is that most available already made products are so expensive that it almost forces you to make it yourself if you plan to use it at effective doses or for more than one person. If it is for a family then a generator is definitely more practical.
Many manufacturers make a big issue out of the fact that they sell their products in amber or blue bottles or in glass bottles, but the fact is that if the product really is "colloidal silver", then there is no need for that. Colloidal silver that is properly made does not change or degrade by ultra- violet light exposure or exposure to proper type plastic bottles. Often times these products are ionic silver and ionic silver can change when exposed to uv light. Most silver studies are done using colloidal silver and occassionally they will include ionic silver as part of the testing process, but the majority of publicly available studies use CS. Both forms have beneficial health effects, but in the majority of studies the ionic form seems to be more toxic to normal human cells. My preference would be to use nano colloidal silver and that is what I make at a moderately high ppm for the sake of convenience.
Another consideration is parts per million. Some manufacturers make a point of making 10 ppm as opposed to the more commonly available 20ppm, but they charge about the same price as their 20 ppm counterparts. If you want 10 ppm it will probably be more cost effective to buy a 20 ppm product and then add an equal amount of distilled water to it to make 10 ppm. If it is true cs, it will still be true cs once the distilled water is added.
Most products that look like clear water are likely to be ionic, but cs that is of very small particle size less than 5nm can also look clear, but I doubt that there are many manufacturers producing that size cs because that would raise production costs considerably. In many studies, cs in the 10 to 25nm particle size is generally a good effective size range. Going much smaller can have adverse effects on human cells and going much larger can be less effective. Most products are actually in a particle size range and are not all the same size. A well made product might be in the 10 to 20nm range where many studies show good effect. When a manufacturer states a specific particle size, I would assume that it is an average or a mean. To get just one specific size particle would be difficult and would probably require filtering that would add considerably to production cost. Some labs will sell such a product, but it is very expensive.
I use a relatively expensive generator setup, but it has features that I wanted and so I was willing to pay up for those features and convenience because I make a significant amount of cs, but there are reasonably priced generators out there for less. One feature that I would consider a must for any generator is "constant current" because this will allow you to fairly accurately determine the parts per million of every batch you make and should help you to make uniform batches with repeatable results each and everytime.
Once you start making it on your own it is easy and your generator should pay for itself fairly quickly.
