Low potency - I've had no issues or side effects with the 120,000 unit version - so taking multiple doses of this one just made me burn through the bottle that much quicker. I'd highly recommend a higher dosage, as there are no discernible side effects from serrapeptase. This label seems to hold up to one of the more powerful brands I've tried. I'm happy with the purchase but did go back to a higher dosage as soon as this bottle was gone.

Swiffer is very poorly built. As if they made it to last up to 3 months. Top handle breaks off so easy. It is made with poor quality plastic and it is very thin where it connects to metal rod. Once floor is cleaned there is some sort of thin residue that attracts dirt and makes hardwood dull. Considering quality and effectiveness this product should be rated 0. Have "experts" at P&G ever tried to use this product themselves?
