It's a useful addition to your toolbox if you have air dolls lying around.
However, it's a bit noisy when pumping air with it, so if you live with others, they will probably be able to hear it from nearby rooms.
Outside of that, it does its job reasonably well.
This Foot Air Pump is discrete to hide, but not discrete while pumping air into inflatables. Others will notice when the foot air pump is used based on the sound it outputs.
Luckily, it is cost effective for what it does and saves some time from manually inflating air into air dolls/pillow products or investing in a electric air pump.
Likewise, if you are already purchasing some items, I recommend adding this to your cart since sooner or later this pump will be an invaluable asset for your collection.
