So sad, to purchase this Black and Decker hand held vac. Always great products, just with this hand held power switch and closing button lock, this device is not operable. Purchased at Walmart ( Greenville Pa. ) and discarded my purchase cash register slip. Why not, Black and Decker, was always a great product. Cost $ 59.00 March 2021 refund and still have product and box. box number HLVA315J62 bar code [protected] Thanks, for your help. Charles Wilson 171 N. Maysville Road. Greenville Pa.
