With all due respect, your entitled to your opinion, but if other people are posting that the low ppm products are not working form them, then they should know about this product that works.
Heck, I do not care if people make their own CS, I made my own for years until I found out about the side effects of the home made CS.
In fact I will post a method of making your own CS with out expense kits very soon.
Its easy!
But do I recommend it no, because I know that they do not work.
