I had been eagerly awaiting this pump ever since I saw everyone using it at FLOAT. I did a side by side of how long it took an 11in latex to inflate with the pink pump vs the air force, and the speed on this is next level. I did a huge job in half the time, and wish I would have purchased this sooner. I haven't figured out how to inflate a 260 balloon yet like the instructions said, but I'll figure it out. It blows 5in so fast that it takes a second to realize you barely have to touch the foot lever to get it to inflate. BEST INFLATOR EVER!
