It's kind of weird but I'm getting used to it, especially finding flavors I like. I think you should put the 7-flavors package much more in front of your landing page as different people will surely like different flavors. (Favorite ones so far: banana mania and super strawberry)
I've seen that you have experts as advisers, with the money you would be making right now I would consider hiring them (or at least one of them) full time. This will make the team look way more professional, and the company as a whole more professional.
I'm currently writing up my experience with Queal and will post that as a blogpost sometime in the future (on one of my blogs, davidwong.fr) so if you want beta testers for new products I'm in :)
Feedback after a week of use:
* I can make 4 shakes out of a bag. I might be doing it wrong. * Shaker should be deeply washed on first use, I badly washed mine and I had a awful taste in my first shake. First encounter is very important. I think you should write it down in your pamphlet as the first step. * sweet tastes, a lot of chocolate taste. It's weird to replace a salty meal with something sweet. A lot of the flavors are too sweet for my taste and I end up adding more water most of the time. I wish there were salty tastes or more exotic taste. There are so many shakes possible with other vegetable or fruits (mango, avocado, tomato...) * researching salty flavors? Check Horchata (mexican) and salty lassi (indian). Lassi has other flavors (like rose).
