For me, AmiAmi's packaging of my DX Chogokin YF-21 was the best I had ever seen, done in such a way as to guarantee that no pressure could be applied to the YF-21's actual box top, thus mitigating risk of pressure being applied to the head laser/antenna that has infamously been bent for some folks.
My DX Chogokin VT-1 from Yoyakunow looks to have tentatively arrived with no problems, though I would not say that their packaging was done as well as AmiAmi's, YYK's shipping box left small space margins for the VT-1's own box that were filled with crumpled newspaper, whereas AmiAmi's shipping box provided a huge gap beteen itself and the YF-21's box top, so that even penetrative impacts to the shipping box would have difficulty reaching the YF-21's own box.
While I am glad my VT-1 from YYK tentatively arrived okay, I do feel that a little bit of bad luck could have changed the result, whereas I feel like a lot of bad luck would have been required to damage the YF-21 from AmiAmi.
