Upside: They are delicious, Low carb, and very creamy. Taste just like Reese's only not as oily. I loved em. Great treat to bring in a movie.
Downside: They are small, about 1/3 smaller than normal peanut butter cups and kind of expensive. Reese's makes sugar free cups you can get in a bag but you can't eat that many of them. They are a little cheaper though.
Still, if you want a treat and need to fill a sweet spot this is dead on impersonation of the real thing. You can't go wrong.
