Stroller naps used to be a battle until I started clipping this to the canopy. The sound is loud enough to mask traffic but not so loud that it bothers me, and it survived a whole weekend of errands on one charge.

The clip actually stays put on the diaper bag, which I wasn't expecting since most clips slide off. My daughter knocked out in the stroller during a loud restaurant dinner, so it's earning its keep.

We've used it on two road trips already and the white noise completely drowns out car engine sounds. It clips onto the diaper bag easily, though the strap is the real winner for keeping it within reach on the stroller.
