Review on Portable Lightweight Cordless Handheld Cleaning Device by Jeffery Pricinoc

it is useless. The "lock" mechanism doesn't work and immediately falls apart at the SMALL moment of pressing. You can't use it. Suction power is ok. but you can't use it. general. When I used it, my return policy had expired. The lock is a plastic groove of half a mm. You undo it twice and the half mm edges are now round and do absolutely nothing. I'm so mad I wasted my money on this crap.
