always works. drink water a few days before the test, it lasts anywhere from 3-6 hours depending on your metabolism. Make sure you drink it 2 hours before you're expected to pee. For one of those hours keep drinking water and peeing so it gets built up all the way through your bladder. By the time you take your test you should have drank the whole drink 2 to 3 hours before, this way you're right in the middle of when it's most effective. Pro Tip: Let a little out into the toilet bowl, then fill the cup mid stream. That, from my experience of doing this with this drink over 10 times, is what I found to be the best formula.

I received this exact set of knives many years ago as a gift. I have lived the set and it's still like new, knives are still sharp, and I use it everyday. I was excited to be able to send one as a house warming gift to a friend however when I saw the set I was disappointed. It didn't seem to be as sturdy as my old set. I'm hoping the quality of the knives have not changed but the entire set looks cheaper and smaller than mine. I won't order another set of these knives even though I love my original set .

Do not buy this. This is very very cheap prouduct. Mine failed (motor was dead without warning or symptoms) within 5 months and customer service told me to pay 33% of the cost of the new unit. Ninja product warranty is one of the worst . Please read warranty carefully before buying Ninja products.
