Broke after a month
In my quest for leak proof travel bottles, I tried the Pitotubes.  Two out of 4 used gave me trouble with a very liquidy cream.  One broke, the other was difficult to dispense, even after repeated interventions.  The other two continue to work fine after a few months.  However they are not very easy to refill, and they take up considerably more space than other products that hold the same amount of liquid.  Very disappointing.
