So my valve arrived and I tried it last night and for part of my morning session. There's pros and cons to it, and I actually took it off and went back to the annoying norm during my morning session today.



Pros: 

• It works. It maintained the pressure when laying down without me having to repump it and it works better standing up and moving than w/o the valve, but still not perfectly while moving
  

Cons:

• You can't reduce the pressure or release the pressure after you pump it up. You actually have to now manually remove the cup from your breast when you don't want it anymore because either you're done for the session or it becomes too intense
  
• It doesn't work perfectly when moving. This may or may not get fixed by adding a bra to it. Sometimes when bending especially it starts to become detached. It def works a lot better moving, but it can become detached esp if you bend your chest in any way (like trying to get back in bed to lay back down after being up) and when this happens it's more annoying because you have to reattach the pump to start pumping it back up. I do think adding a bra (like maybe a nursing bra because it has holes already) could resolve this problem by keeping the cups from becoming detached when bending and a bra would also hold the little tube that will dangle (but isn't attached to the pump so isn't heavy).
  
• It uses up both noogleberry tubes so I'd imagine you'd have to buy another set of tubes if you want to do both breasts at the same time. It was fine for me for right now because I'm only doing my small breast so I'm not doing both breasts at the same time.
  
• I started struggling with it wanting to cut off circulation and my breast going purple/blue repeatedly. It turns out (in my case at least) that it losing some suction and having to be repumped w/o the valve was good for me in that it was keeping circulation from getting cut off, but when I had it on a constant pressure circulation kept getting cut off resulting in me having to manually remove the cup.
  

I actually had the best morning swelling left over from last nights session despite having to do 1 hour less than normal in my nightly session (due in part to my last con on the list) and me getting a late start last night. I did go back to the usual w/o the valve in the midst of my morning session due to the final con on the list though. I will probably try to reattempt it in the near future. The only con that is a dealbreaker for me is the last one obviously, but I very easily have the circulation getting cut off problem which is why I'm doing longer sessions w/ less pressure to begin with and that doesn't mean other people will have this problem. The first three cons aren't that bad and are easily fixable. 

I got the Pawfly Aquarium Air Pump Check Valves Plastic One Way Non-Return Check Valve off of Amazon for 5.42$ that came with a set of 6, so it's a really cheap experiment. That's just the one I used though obviously any valve would work. If you don't struggle w/ your circulation getting cut off then the first three cons are pretty easily fixable or not that bad to deal with. At the end of the day it works in maintaining the pressure and last night I even noticed I got a better and longer swelling despite doing 1 hour less w/ it but the circulation thing was a problem for me. I'll try it again in the future if I can get my breast to stop occasionally cutting off circulation w/ normal pumping.
