I have had one of these a few weeks ago.
Came on after 45 minutes, and it was a really really nice pill! VERY clean feeling. I was pretty luvd up, hugging all my mates, talking a lot, but also, for the first 45 mins, it sat me down and smacked me a plenty. A good smack tho, nice and euphoric. I could not help notice that this pill lasted longer than many others I had taken, and I have a strong dedfence to E's. I also kept saying how clean the pill was, and the same goes for my buddy.
I really enoyed this one, just get up and dance after it has smacked you a bit!

PS - I just got 2 more of these, so I might have another go! Yummy!
