I was worried about the low price vs quality but the jump castle was a better than expected deal. The quality of the material, craftsmanship and air pump are fantastic. Purchased for my little one's 2nd birthday and it was fine with 3 kids jumoing around.
Construction quality= excellent
Pump quality and cord length= excellent
Setup= Fast! It fills with air in less than a minute.
Storage= Easy. The bag works well and stores easily.
A few things to note:
-Use the provided stakes to secure it to the ground! It almost tipped over with the kids inside.
-Don't let it stay outside overnight and collect moisture. I did this once and it took a couple of hours to dry it out. It will become moldy in the right conditions.
