My 3 year old asked for a balloons for her birthday so we got hundreds of balloons and filled them all up in about 20-30 min. After the first few balloons you kind of find your groove with it and then it goes by super quick.
My only two complaints: -Noise is a bit loud but not unbearable. It is a freakin mini compressor so I didn't expect it to be silent. -I wish both nozzles could be run separately. If i start inflating on one side, then the other nozzle starts blowing air as well. Its not a big deal if you're working alone, but if you're working with another person you have to sync up when you push down to inflate.
Overall, it got the job done and saved my lungs so I'm happy.
