I've got the Balsamic one, its okay, but nothing to write home about - you have to spray quite a lot on to be able to taste. Okay if you are in a hurry, but when I have a bit more time I prefer to make something up with balsamic vinegar/lemon juice/mint sauce/chilli etc
What is good though - it lasts ages (and doesnt go off as far as I can tell) Even though you have to spray loads on, the bottle still seems really full (I must have got through 4 or 5 bottles of fry light in the time I've had my bottle of salad light - okay, I use the fry light more often, but I still think that tells you something about how long it lasts)
