Sorry I saw this so late, are there any lingering questions. The formula was indeed made with the consumer in mind...who else would be in mind when we made it? Getting a totally novel and never before used ingredient was expensive and time consuming. Not just manufacturing, but actually finding something this effective in nature took a lot of time and energy. Several users and our testers liked it better than the old erase; similarly, many users prefer the old Erase. This is what happens with any product revision.
A great example is Slin sane. The 2nd version was way better than the 1st, but people demanded to have the 1st back and so they reverted. Another example is AMP v1 vs v2 by E-pharm. And the list goes on. It comes with the territory of changing a formula people love.
The difference here is that those two brands reverted to formula #1 because of the feedback. For us, the feedback has been mostly positive (remember, there's a large world outside of the forums and we're carried at the 3 letter store too).
The science and anecdote both back up Erase v2 over v1, and while we can't please everyone, when all things are considered, this is certainly an improvement over the previous version.
