I haven't use them yet but tested them. I think the products deserve a 5 star even though it might or might not work for my boys. Overall they look like very quality but I do have some feedback.
Pump - Can be dangerous and make sure you keep it away (far away) from children. I know the fan on top is necessary, I can't fit my finger into that hole but my son definitely can. When pumping, the fan spins fast, I think a few thousand rpm and the fan is kind of "open".
Bags - The bags are very good quality. The package arrived slightly damaged which I believe it was being cut though by something sharp. The bag protected the items and I can see a mark. However, they are just very small. With the Kloud, you really have to fold it up properly and tightly then squeeze it into the small little bag for it. Even though how hard I tried, I still couldn't close it up nicely. Even the big bag for the Kooshion, is slightly on the small side. I can imagine with both my toddlers screaming at me in the flight, it can really be a hassle to pack the items properly.
Headphones are slightly on the bigger side but I bought the clips so it works for my younger son.
I do look forward to using them on my 8 hours flight next year with my boys!
