I use it on 3 o'clock with the L domes and its not uncomfortable at all, even after a whole hour. They do go a bit reddy and mottled but this subsides after 5 minutes :-S Have been using BB since April 30th, so start of May really. Is the suction not as strong as it should be?

Anybody? I want to know if its tolerance or the suction isn't as strong. Its been used for two months now you see, and I use it for four hours a day (I do each breast separately, twice).

It sounds like tolerance but I don't know that any of use can tell how strong the suction is since we are not there to test it or feel it for ourselves. If you turn the suction down to where you had started out and then place your finger over the left valve can you feel it make a seal? does the middle one make a seal? if you turn the suction level up gradually does the suction increase or stay the same throughout? That might help you to figure it out.
