This cute little device is very useful for removing all the crumbs from the dining table, as well as cleaning laptop keyboards and similar small surfaces. The suction power is enough for these items and the whole gadget is easy to handle; The only negative is the instructions: it's in Chinese and incomprehensible drawings; The most uncomfortable moment was installing the batteries: the ladybug needs to be held with one hand, touching the bristles of the palm, and with the other hand gently twist the upper part until it shifts and the battery compartment appears. Very clumsy.
