I can't believe I'm about to say this, but I, for one, could not be happier with the Magnesium I've bought from ChemMaster. (As far as one can be happy with these things anyhow.
) No hesitation to buy again when I run out, and happily recommend the service to anyone else. Seriously, look at the cost of liquid Magnesium additives and see how long a bottle lasts you ... then buy a box of the powdered stuff, you won't look back.
