Haven't tried it, but from what I've read, it's very hit or miss, and mostly miss. Usually the first batch is decent, then thereafter they send you all the crap that doesn't sell and people find it really hard to cancel their subscriptions.
Like I said I haven't any experience with it, but maybe do a little research. They do a hell of a lot of marketing though.
All of their juice is really bad. I had maybe 13 of their gold boxes and was very disappointed. Don't waste your money on zamplebox!
Edit- I see some ppl made bad comments(RIP ENGLISH) please if you don't have anything nice to say rather keep your mouth shut. I was driving when I posted this reply and sorry made a couple of mistakes.
