Bests & Worsts Reviews from Amazon

Not as discribed. I have bought the 500 ppm. I poured out the whole bottle in a sterlized glass beaker to see the true ppm of this and it wasnt. It was 300 ppm. Also Before i even tested it i calibrated my ppm meter to make sure its acurate. Then after that i filled up a 16ounce glass bottle with reverse osmosis water to dilute it but when i put couple drops it shows nothing then i kept adding more drops still nothing after that i brought out my other ppm meter to see if it makes any difference NOPE its the same so i decided to pour the whole little bottle in and only showed 20 ppm lol i was like what the F. I have done this before with all other brand colloidal siver and this is the first time it came out like this. So im pretty sure i got a deffectded lil bottle of this. Also i was wondering out of all the colloidal silvers this is the dark yellow. I didnt even wanted to test drink the diluted colloidal silver because im afraid this might not be safe. So bam in the sink it went.
