These things are great! I have a small lawn mowing business and I'm always strapping and unstrapping the mowers. At the end of the day you'd be surprised at how much time is saved by simply pushing the return button and the strap snaps back into it's body. I always rolled up the straps so I didn't end up with a big snarled up mess of straps. No more, seconds later the straps are back in the tool box ready for the next day. What a time saver.
