Iv seen 3 different variations of the Ecstasy by wampler, and now its called the Euphoria or something? anyway, im wondering about the original really blank looking version with just "ECSTASY" wrote on its front, the rest of its black, then the more modern greenish one with the letters wrote in a font and now the Euphoria. Can anyone answer me as to what the differences between all of these are, because in my experience, many unlisted changes occur between appearance modifications.

The Euphoria and the previous Ecstasy are the exact same, they changed the name to differentiate it from other products on the market.
Not sure about the the early Ecstasy model, I'm guessing its the same, but don't quote me on that.
