This product had pretty good reviews so I thought it would be safe to buy 4 packages, so I did. Boy am I full of regret now. I'm stuck with 4 packs of these beans and I can't return any them. The moment I opened the bag, I should've known. It had a stale sour smell to them. But the optimistic side of me said, these beans look fresh and plump, maybe it won't smell like that once I scrape the seeds out. I was wrong. I made two test batches to see if it was the salt I was using to make my vanilla salt but they both have that weird sour, rancid smell. I've made vanilla salt before so I know what it's supposed to smell and taste like. Unfortunately, even after a few days, this smell isn't going away. I was really looking forward to making jars of vanilla salt to give out as cheap gifts. But now I need to go buy more vanilla beans to replace these which is going to end up costing me. I'm so disappointed. I haven't cooked with these seeds so I don't know if the taste and smell transforms with heat or with any other mixed in ingredient. I know for sure though that if you're looking to make vanilla extract, vanilla sugar or vanilla salt, I HIGHLY discourage you from buying this product.

I have never been a huge coffee fan. However, my mother purchased this little machine and talked me into trying the Latte Macciato. No Coffee Shop has a better one and I like most of the other products, too (as a usually non-coffee drinker!). The little Dolche Guesto Machine is super easy to use and prepares a really good Coffee/Latte/Cappuccino/etc in less than a minute (if water is heated up). I would recommend the Dolce Gusto to anyone. Too good for the price and I'am getting one myself! :)

Do not buy these for your dog! I made the mistake of not researching Greenies Dental Chews online before buying these. If you Google the Greenies and how sick it may make your dog you will be shocked these are still on the market. Dogs have died eating this deadly poisonous treat.  I saw the reviews on this product and I bought the teenies for my Yorkshire Terrier and gave it to him at night after his dinner. I figured since its for 5-15 lb dogs and his first time, I'll give him just half of the teenie. The next morning he didn't eat and he threw up bile and some of the food he ate from the night before. And remember I only gave him 1/2 a piece; imagine if I gave him an entire piece, it might get obstructed in his intestines.  I complained to Amazon and they wanted to send me a replacement. Seriously? Like after all that for making my dog sick, you think that I should try it again? Plus they wanted the Greenies back. For what? To resell this poison? They wouldn't even mail me a box to return it. Eventually they just decided to send me a refund and that I can discard the Greenies.  I just want to warn pet owners of this danger. There are plenty of similar complaints on this product if you research online. Please take care of your pets!
