This tea tastes almost as good as the tea you would get at an Indian restaurant. It's much better than getting a teabag and making it the English way, with a lot of water and a bit of milk. This is very creamy and tasty. My only criticism is that there aren't enough sachets in the box. Only 10. Since the directions say that you use one sachet for 100ml of water (approximately half a cup), it's not enough for a good cup of tea, so I use two. That means that one box is only good enough for five cups of tea. But it's a delicious after-dinner drink! I would buy this again if there were more sachets in a box.

Only 5mg sodium per serving, chips are crisp.  I sometimes will dip in a low salt ketchup and that adds a bit to the flavor.

I feed Hills Science diet to my pet because I love him and the vet tells me I should. But in all honesty, this product has what is quite certainly the worst snap-lock reseal that I have ever encountered. It is painfully difficult to get it to close properly; and even when it is resealed as best it can be there are still gaps on the side that allow air in to oxidize the product.  Packaging IS important. It is no better for your pet to live on stale, oxidized food than it would be for you. Oxidized fats are also called rancid. If you imagine how healthy a rancid diet is for a human... well, you get the idea. This is about more than just inconvenience.  I am posting this review for all the Hills Science diet products with this kind of packaging. If you have had the same experience as me with this product, please take the time to let this company know about it.  I love my animal. I want to keep feeding him what the vet tells me is good for him. But this quite literally the worst reseal that I have ever had the misfortune to encounter.  Theo.
