I had been using Queal some time a go, then I decided to stop it for a while and now I started to get some wundrbars which in my opinion are better than Queal in terms of pleasure in eating something "hard" or "solid". Queal is instead better in terms of nutrients and to diet as well, as it can replace any meal even in the same day. Personally I had some light digestive problems on long terms, but that's depend on the person and his/her physical condition.
