Convoy S21B rattling issues

Morning

Bought 5x S21B with the Osram emitter. 2 of the 5 rattle at the head when shaken, both with and without a cell inside. I tried to open the head on one of them to have a look but it doesn’t look like there’s a pill there so wasn’t sure how to take it apart.

Anyone else seen this before? I’ve asked Simon about it but not sure if I should just accept this kind of thing with budget lights. In every other way it is awesome.

I am pretty sure there was a pill in the S21B I had

I removed the retaining ring and the board just popped loose, wasn’t sure how to progress to removing the head assembly from there.

Screw it out or try to tight it and see if rattling stops

Liked I said I unscrewed the ring but that just loosens the circuit board. I tried tightening it but that didn’t help.
