Totally satisfied with the product but you should change your carrier. The package was redone by them and one of the bags was open.

Fast and careful delivery. Expiration date long enough to be used again the following year, I grow and collect tropical plants indoors at home and this criterion is particularly important to me because I buy in bulk and do not necessarily use everything during my repotting in spring. The products seem high quality and effective, I am convinced of it, but I have no hindsight as this is my first purchase.

4 stars, the delivery boxes almost always arrive damaged. A better quality packaging would be welcome as the delivery people are not always very gentle... Without this problem it would have been 5 stars.
