Is it possible that there is a leak in the tubes or in the domes? Last night I managed to get them on perfect and I used my hand pump again to get really good and strong suction (to the point where my breasts were almost filling out the domes) and then about 3 hours later in the night almost more than half the suction was gone and by the time I got up in the morning there was none left and the domes were ready to fall off. I don't understand why it keeps doing this, how can it lose that much suction...I don't even move at all during the night and the sportbox is working fine..

I am using the medium wide domes and they are a little wide on my chest but I do manage to get really good suction with a hand pump so I don't think it's because they're too big.
