Not a bad product
I've been using this for a couple of weeks now and it's not bad.  It's different from Crest or Colgate because it really doesn't froth at all so you think you're not using enough if you're accustomed to those brands.  The taste is good, and it does leave my mouth clean.  This particular item shipped all the way from Germany for me.  Not sure if this is standard with other sellers, but it takes a bit to get to you at that rate.  No complaints at all, although I don't know if it's supporting my mouth's natural defenses, I don't think there is any objective way of testing this by just using one or two tubes.
