For people having slow deflation problems, my Hammock V pad held pressure for a week (inside) but the Long Ultralight V I bought from this drop lost pressure overnight. Below is at least one other person who mentioned that it could be the deflation valve leaking, and they showed a picture of an o-ring they put on it to seal it. I went to a hardware store and bought an assortment of o-rings (measure yours and take that info with you), and now both pads hold pressure for several days.

Not the best picture, but you can see where the black o-ring goes. It works for me, and it's inexpensive.
bcw1000Do you remember at all what size it was? I was thinking of just bringing mine to the store and trying a few... But if you perhaps remembered the diameter....

outsideyourworldTake a piece of paper, push it over the plug to crease it to fit the outside diameter. Trace over that with a pen so it will survive the trip in your pocket. Bring that with you. You want a ring that is that size or a bit smaller - stretching won't prevent the seal. I bought an assortment of o-rings and they were not labeled.
bcw1000Ah yea, that makes sense. How is the pressure holding up at this time for you? The other pad I have could be left for a month without needing to be blown up more.

outsideyourworldMine holds air for longer than a week. Without the o-ring it would be partly deflated in a night.

bcw1000I have the same issue, but the o'ring trick doesn't work for me as the valve keeps popping up when I lie on the pad... I might try to cut the o'ring or get a different one. Very annoying. Drop refunded the purchase though so I can't complain, but still it's a waste of time.

geekyhikerYou haven't said, but I will offer a suggestion. If you look at the edge of the fitting the cover snaps into, you'll see that it is chamfered at about a 45 degree angle. The chamfer is also small. An o-ring need only be large enough to fill that space, and a larger one can prevent the plug from snapping in to the socket. Then air pressure alone is enough to push the valve open. The o-ring I chose is only about the cross-section large enough to fill that chamfer when the cover is snapped in, and that provides the air seal. The existing snap lock provides the mechanical strength to hold the cover in place against the air pressure. The perfect o-ring is a little bit smaller in it's major diameter than the plug so it fits solidly against the plug, and the cross section is only large enough to fill that chamfer to provide an air seal. Perhaps you have a an o-ring that is too thick to allow the plug to snap into it's connection and catch well?

bcw1000Yes that's what I tried to do - Tried other o'rings but they don't work either. I'll try a washer.
