This thing really does blow. And goodness knows I love a good job done.Lightweight and small, but punches above its weight. I use the 3 speed settings, located above the thumb. These speeds are set well, Low Med and High. Low moves light leaves, med is a good middle ground, and high can push even bark chips back in place. Note that high really does consume a lot of battery!Conveniently, the good folks at Milwaukee added a lock-on switch, right above the trigger on. The trigger moderates the speed pretty well too, but at this price point don’t expect a ton of precision. The 18v battery is the heaviest element of the device.The attachments are nice add for inflating various pool toys or camping equipment.
