Pros: No batteries required. The kit includes a brush and a charging cable. Easy to use and throw away the contents inside. A lightweight. The nozzle is a great addition. Cons: The suction power is low. Can only hold small items such as eraser residue, crumbs, nail clippings, strings. The grip is a bit awkward, especially if you have big hands. To be honest, this only works well with a nozzle.
