Mine arrived today from Boomkat in the UK - I pre-ordered mine out of an abundance of enthusiasm.
UPDATE AFTER CHRISTIAAN’S MESSAGE:
I tried three different brands of AA batteries (Rayovac, Everready, and a Kirkland brand battery) and none of them fit smoothly and even when I managed to squeeze a pair in, the back lid would not shut without pushing on it. Ultimately, it does shut.
After following Christiaan’s instructions, the machine turned on. Long push to turn on. . .long push to turn off. Flick up and down on the wheel to change stations.
I suspect there is no volume control on this one, which complicates using it in concert with the previous generations of Buddha Machine, but thankfully that was not my use case.
I’ve wrapped it up and will give it to my wife tonight.
Phew.
