Great little blower that exceeds expectations. Sized to fit into a large hand, but could be squeezed equally well in a small hand, this blower gives a short blast of air capable of clearing debris from difficult to reach corners. Works well on keyboards, circuit boards and cameras, I bought this one for clearing the jet on a camper fridge that is prone to block. Well made, sturdy construction that feels like it will last. The one way valve works well for rapid re-inflation so that the bellows inflate immediatley upon release and do not leak when squeezed.
