Clipped it onto the treadmill handle during my morning run and the 8-inch head kept up a steady breeze without wobbling once. The clamp is genuinely sturdy, and the 10000mAh battery has been running for days of desk use before I even think about recharging. That fourth speed really pushes some serio

Used this clipped to my desk while working from home and the 4 speed settings make a real difference when it gets hot. Battery lasted a full 8-hour shift without needing a charge.

Brought this on a camping trip last weekend and the battery lasted through two full nights of use on the medium setting. The clip held securely to the tent pole without any slipping.
