Although the nature of Purux-soda, which the Bielefeld manufacturer like, there is a difference. Purex lumpy and not something that from Bielefeld.
In all fields of the effect, however, is identical and even heartburn it helps almost as good as expensive soda or Natrontabletten.
2 points I pull off, because the shelf life is only just over a year, so only until September 2012. For such a large amount of 5 Kg far too little. This can be attributed only to a longer storage time after manufacture. Because I still have a small pack of soda, a well-known manufacturer that I bought months earlier and by October 2015, durable and a remnant of the Bielefeld Fima, which holds up to early 2014.
With such a large amount of soda is the shelf life of only just over a year, designed much too low. As should be improved, because we are still customers in the belief that it is so large amounts of soda to freshly produced goods rather than old stocks is. This could also explain why it clumps somewhat.
Review the current delivery from July 2012:
Now, after more than a year, I have reappointed me Purex soda and am fully satisfied this time. The delivered today soda is 2 years. For such a big quantity of 5 kg now durability is for me therefore entirely sufficient, even if a manufacturer Bielefeld 3 years Emperor 4 years, indicating their soda. For this is the opposite of delivery over a year ago, perfectly pure baking soda with no lumps.
Because the quality has improved by probably longer shelf life, I raise my rating on full 5 stars.
Review the current delivery in April 2015:
With such a 5kg bucket I keep from approximately 1 year. Be my last review in 2012 and since then a number of other orders is at the very good quality not changed. Besides since 2014 the packaging. The has improved. The bucket can be since opening much easier. All soda-buckets I had appointed until 2013, sometimes much effort was needed to open it.
