The quality of the product is not up for discussion. That's very good. I use it for years on my Bankirai-ground in the garden. Very poor was the packaging. The can be worked out by a whisker during transport. It took just a little lever with the screwdriver and it was open. The transportation company, which has probably treated the first package with the can somewhat rudely (my guess, based on the state of the box when unpacking) would have certainly pleased, would be if the oil in the transport vehicle rumgelaufe.
