Flirt with the "too long" time. If you play it safe the suction isn't strong enough
First it wasn't working in the suction was really poor and they tell you did not leave it on the same place for a long time that's how I first thought this wasn't working very well. However, if you flirt with the time as in you left it on too long to just the right amount of time you will get suction.
