I bought these pill case stackers several years ago, when they were a little smaller and made of an entirely different grade of plastic. This version, which is bigger, is made of an extremely brittle type of plastic that breaks with even the slightest bumps. Pieces of the plastic -- particularly the threads that screw on to the other containers, regularly break off into our vitamins. This product no longer has any quality. Do not waste your money.

Shortly after I began taking this product last Fall (after switching from Enzymatic Therapy brand), I developed horrible acid reflux and a gnawing/burning pain in my stomach. Not realizing that this supplement was the cause, I began taking Prilosec last November because the symptoms were so severe. I also eliminated all of my extraneous supplements, but continued taking my multi, fish oil and calcium. Still, I found no relief and could not even go a single day without the Prilosec. Then, I decided to retrace my steps and figure out exactly what I did differently just prior to the onset of these symptoms. Switching to this brand of calcium/magnesium was the only thing that was new. I stopped taking it a week ago, and can now go without the Prilosec for the first time in 5 months!!! I don't know if my reaction occurred because the product was spoiled or because the ingredients. After this experience, I have to say I will never try anything in the "Now" product line again. I will stick with Jarrow and Enzymatic Therapy.
