Razer Basilisk V2 construction problem!!!!

I'm at 3 returns if I do it again this time. I can't find a Razer Basilisk v2 mouse without even a build problem. The first ones I tried had problems in the important keys (left and right), wobbled, weren't stable, and were croaking. With the last, the keys seem to be fine for now, but the front body at the height of the logo, when I put my hand more heavily, it makes noises, it is not assembled well, in fact underneath I can see that there is space between the front body and the attachment, touching it, moves and makes noise. Can you explain to me why they don't do quality control on this model? It costs not € 20 but € 80 and it is a huge shame. Now I have to return for the third time. Do I have to assemble it myself? send me the pieces I would do a better job ... I order products on Amazon EU, and never had these problems with the competition.
I pay for the quality, I have no problems, but at these prices I demand a perfectly assembled mouse. Instead, after 8 days it already croaks like a toy....
Disappointed and angry!! Wow..:mad_:
what's going on Razer? o_O
