I have just received it, and not to mention its primary function I see that it is not very silencer.
For a measurement at 1m as it should be, I raise 48dB and not 35dB as indicated on the site. The packaging is very minimalist and I received the item in its original cardboard completely crushed. Chance he didn't break, I'll see if at least he does what he's asked of him and how long. Almost a month to receive the article is too long.
