Super product, but just not a craft glue, as some probably think here ..

The many bad reviews are due to the total misapplication. The adhesive achieves good results and the instructions are for more than adequate.
On both sides and allow to dry. It is probably logical that the dosage should be minimal .. A thin primer film is going to create. Just take a toothpick and then pass. Very easily. The glue is drying, and not curing. So wait about 5 minutes and the thin film is dry. Now again thin film adhesive to one side now, pass and hold together parts. Little remains of which can be expressed after curing the next day with a knife by scraping.
If you do it right, it works fine and without problems ... It's just not a craft glue .... just like 2-component adhesive ...
