A dark option.
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
I decided to try this--I like a robust, rich flavored coffee. The color of Happy Belly Dark is good but the flavor a bit lacking for me.

Remarkable Quality at that Price!
Flavor Name: Dark Roast, Size: 24 Count (Pack of 1)
Look folks, it’s not Barista Prima or Starbucks, but it’s very inexpensive for what you get. It’s strong and tastes pretty good and will wake you up. What more can you ask for?

Amazon refunded us immediately; we requested credit
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
This coffee was great tasting, the aroma was nice, BUT the containers were the problem. Amazon took care of us right away and refunded us; they didn't even want the rest of the coffee pods back or proof of all the ones that burst open in our coffee maker. Here's the only reason we snatched off two stars; the foil tops came loose ( in all the Happy Belly Flavors we purchased) while in our keurig/pod style coffee maker. Grinds were in the cups of coffee and all over the inside of our coffee maker. We decided to try to not waste the coffee after Amazon said to keep or throw away the faulty product, so we, one by one open and pour the Happy Belly ground coffee(s) into a 12 cup coffee maker basket when we have lots of coffee to prepare. The coffee itself is delicious and fresh, but something's wrong with the packaging's foil pod tops on all the types of Happy Belly we bought. Too bad, because it's good coffee, priced at a bargain, it's just too bad the pods are falling apart messy.

Delicious coffee. Had a fabulous price
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
I've used several different coffees over the past 12 months, including french press. I find these pods every bit is good or better than the other coffees at 3:00 or four times the cost
