Leaking Bottles

If you have a MAM Anti-Colic bottle, does yours leak?

Its so annoying. I know I?m screwing it on tightly enough.

Does it have an inner anti-air piece like Dr. Brown's or Tommee Tippee? Sometimes they will leak because liquid gets into those pieces and can leak out the upper vent air piece.
