It was used in the summer on the balcony in the afternoon hours.
It was inflated using the Intex Double Quick II Hand Pump, quickly and without much effort.
The inflatable bottom is great. Even this little bit makes a big difference compared to others that don't have it.

2 kids, 4.5 years old, and 1-2 babies, 1.5-2 years old, played nicely and had a great time.
Time will tell about its durability - if it lasts 2-3 summers, I will be satisfied with the price and would buy it again

Great plus the inflatable bottom. Although the sides are not very sturdy to hold the weight of an adult for example - for kids it's fine. Three kids, 6 + 2.5 years old, were playing just fine.
