Actually you sent the same flavour of Demon twice, the orange coloured one that was tropical flavour? And yes, the white was was NOS, I'd forgot but it was one we were watching on the internet then you sent one x3 I have tried redbull, over here it is one of the nicer shots, I don't know if they make them different over there, over here it is pretty strong but has a really nice after taste of red bull.
The NOS, i'll have to get back to you on that one, I've got it all written on a rating chart in the back of my diary upstairs ^^;; I can't remember offhand so I suppose it wasn't disgusting, i tend to remember those ones to avoid them XD
