I've had to use the drop down oxygen masks in a decompression.
All the masks deployed, but as it turned out mine did not have any oxygen flowing to it (although the 2nd mask which my colleague was using was fine). I had to move into the cabin and use an extra passenger mask.
I was not aware of anybody else reporting any problems with their masks, and from memory the bag had torn away from the mask.
I know I managed to dismantle several carts and secure the galley in about 20 seconds flat (but have no idea how looking back), which I am sure was entirely because of adrenaline kicking in, and my extra strength at that moment in time may well have been the cause of my damaged oxygen mask.
Luckily all ended well with no further dramas, but my advice would be not to pull the mask too hard!
