Weak points:
-L'odeur! Upon opening the package, there is a strong smell of chemical given off. So I set the OPEN package out, and after three days the smell is gone. It remains slightly on PCBs, but you really have your nose stuck on it to feel.
-The Shipping time (but deadlines are met)
-If Heated too long, the copper pads come off.
CONCLUSION:
Despite the smell and some small flaws, this is very good for its price, it is for this reason that I did not remove star (s).
