I was surprised how much this tasted like watermelon! The flavour lasted about 30 minutes, so about what other gums would last. I would prefer it didn't have citric peel in it (they do make other flavours that don't). I'm not sure whether this would offset the tooth benefits of the xylitol. I ordered the wrong one accidentally here, but it is still really delicious, and worth having as a treat. They did such a good job with the flavour!
