We've only used this once, but it kept us awake most of the night.  We were surprised because it's decaf, but we couldn't sleep for hours after going to bed.  Tastes good, though.

I bought two bags of these, thinking it was the same product that I used to buy in different packaging (light blue, with a see-through dog shape against a grass green background). Unfortunately, it was completely not the same thing! These treats were actually like jerky-- tough and brittle. I give my dog soft treats because he doesn't chew the damn things, and he choked on these horrible things; I had to toss them out.  Note that the "Zuke's Jerky Naturals" with the other packaging (http://www.amazon.com/Zukes-Jerky-Naturals-Beef/dp/B00008DFPY) have always been moist and soft, and I've never had a problem with those. I suspect that this batch was not new packaging, as I had thought, but very old packaging; these may be the same treats I usually feed my dog, just having sat on a shelf for years. In any case, these were COMPLETELY different treats, and not safe to feed my dog.

That is right, open the bag and just get your nose close and smell it. You know this is a quality product instantly. Some of the tastiest tea I have had and the Oolong and orange are a great mix. Even if you aren't a tea drinker at all, once you smell this tea you will want to try it. I am very glad I bought this product it is a favorite of mine.
