My craptastic stefans: 45 feet
Dart tag darts: 43 feet
Normal suction cup stock darts (the ones that came with the nf): 21 feet
Over all they outshoot the normal suction cup darts by far, and have very similar ranges as the stefans. I also find the pouch that they came in quite usefull

By the way dont try and peel off the velcro I tried and after about 10 minutes gave up.
