Ordered, received promptly and unfortunately once again back!

I would like to be interested by what characteristics (criteria), quality assurance in home Lurch judged this article and decides when an item is allowed to leave the factory or not? What is the purpose of this eingentliche pliers? I am of the opinion that these pliers the barbecued food is mainly designed to grab by the "hand strength", and then to let it through the built-in "spring force" to get rid of. Access is not a problem, but as a good piece of the forceps is going on again? In short, the spring is present, but the tongs by itself can not open, no chance! The spring is designed to be very weak and thus contributes to the actual purpose of the tongs at nothing. Too bad, purely visually see the forceps really good and also has a high-quality appearance. The lock works fine, but everything good brings nothing if the eingentliche function is not given. Maybe it was a Monday-tong? I have returned the items immediately and I will look for another pair of pliers. Thanks for the smooth transaction and quick shipping.
