I read a lot about it being harsh but like every experienced traveler here says, if it's harsh or unpleasant it's because you burned it, I had my fair share of burned spice which is horrid harsh and burns.
But since I found the sweet spot to vape it properly I just have to say that the flavor is incredibly good: flowery yet a little synthetic, warm and very pleasant is how I can describe it. It's actually the best tasting thing that I've smoked so far.
So here's my advice for newbies like me: Listen to the experienced travelers, they know what they are talking about

. If it isn't pleasant and you don't feel like you can hold it in forever, you are doing it wrong.
