[Q]: This tastes like liquid splenda. The aftertaste is horrible. Now I'm stuck with two bottles of syrup that I don't want to throw away because they cost money and I know will stay in the shelve until I give up. Bought it after a FB page continued to rave about it but obviously she's getting paid because I don't know how else you can recommend this product. Monk fruit is not a tasty sugar substitute.

[Q]: The package arrived with two authentic-looking vintage controllers. I tried them with a few Steam games from the 16-bit era. I didn't get past the menu of any of them. The controllers register a constant input. From where? Who knows. It happens with both controllers. I even took them apart and removed all the buttons to try to isolate the problem in case something was making contact. Even when nothing is touching the board, it has the same problem. I have no idea how this product has more than one star.
