very disappointed 293 1

I am very disappointed by this article which trigger broke at the 1st use (impossible to complete the staining my pants)
the seller has nothing to share advice and instructions kind you have to press the trigger, watch the video demonstration
despite my best efforts the product has never walked again
So despite the fact garbage is left open inside

the reaction of the Amazon was also disappointing because my AàZ guarantee request was rejected

I thought defective products must be exchanged at least that is not the case here
