I just received this product has now, I must say that I am not expecting either to something extraordinary reading some reviews and especially given the price ... But then, it's still serious ! Product sent in plastic bags, not even in a box (though it can go), but then the pistons that do not work and are already broken even without having used, I find it outrageous, it would not make fun of the world under the pretext that the price is very low! Some die parts have black spots that senlève rubbing ... Only positive: quick delivery. I rarely makes negative comments even if the product is not completely to my expectations, but it's not possible!
