[Q]: I have been using this product for about six months. My thyroid seems to be both overactive and underactive at times. I have tried many different supplements in hopes of staying off the prescription medications, and this one is working the best for me. I think it took about 30 days for me to see results, but I have felt pretty much stable. I sleep through the night, have consistent energy and my mood has improved. I would highly recommend this product to anyone with thyroid issues.

[Q]: I don't know how it works, because I didn't get to use it. The box was wet on my porch, and inside the bottle of stability was cracked around the bottom edge and had leaked out. Very tired of getting wasted/damaged products from poor shipping practices by Amazon! Amazon should be refunding these things, but they don't seem to care.

[Q]: This unit arrived in good condition, via double boxes. The one minor issue is the poor quality of the 4 screws (included) to support the mirror. Recommend replacing them with American made screws. Recommend installing a Plexiglas top to protect the desktop BEFORE mounting mirror. Otherwise, excellent unit for the price.
