Approximately how many times do you have to pump these? I removed the ring on the 2 ltr bottle, and after 30 pumps, still no pressure. defective?

We opened one and tested it on a 2 liter bottle that had about 1/3 of its drink gone and it took about 12 pumps to work. However we did leave the ring on our bottle. If you have the ring you may want to place it back on and try it (probably won't help but no harm in trying). I know that it depends on how full the bottle is as to how many times you have to pump it. Also try holding it slightly at an angle and see if that helps.

The pump only seems to pump air at the very end of the stroke—like the last 3mm. Is this normal?

Yes, mine is much the same. Doesn't work exactly like a bike pump where it feels like air is being pumped during the full stroke. I've had mine 8 or 9 years and it's still working great.

Is it good for the internal part of the cap to be in contact with the liquid inside the bottle? Like when you store the bottle horizontally.

I have never stored a bottle like that, however there have been times when the bottom of the fizzkeeper has made contact with the soda and I have never had a problem. I would think it would be OK.

Why is there a warning label that says it contains chemicals that have been known to cause cancer? Which chemical is in this device?

probably because it is made of plastic or i hope so just like the plastic bottles you use it for HaHa
