It really is labelled as "XD" on its packaging, hahahahaha.... Cost SGD 28.35, it is way cheaper than the authentic DX, which is stupidly expensive...
This has the same critical flaw of the bootleg Grand Zi-O Ridewatch that makes this not really compatible/interactive with the DX Ziku Driver - the side activation button lacks the double press feature to activate the henshin sound from the pre-henshin sound. This is critical as the DX Ziku Driver has the mechanism to push the side button TWICE in 1 rotation. A Bilibili video owner says he manage to overcome this by making the side button less sensitive to pressing. I tried to open up while fixing the stuck button but could not access to this switch as it's cover part has been glued tight... Anyway, I though maybe can just add another push switch (in parallel) to the side button and locate it somewhere where the belt wearer (my nephew) can conveniently press it to activate the henshin sound.
Yeap, have also ordered another one for myself as this is meant for my hephew.
