TERRIBLE. NOT a new product.
ABSOLUTE WASTE OF MONEY.  TERRIBLE.  I DO NOT believe it was new. Received NOT in packaging, just loose in the box.  I used it once then recharged it and it was totally dead.  This has never happened to me before.  I bought a swivel sweeper more than 10 years ago and used it every day with no problems.  The battery was still good, but the bottom of the dust tray was accidentally thrown away.  I could not order a replacement part because on the sweepers today  the door on the dust compartment remains attached to the unit.  So I bought a new swivel sweeper which I used for several months, again with no problems.  Then the wall charger was lost so I ordered this replacement charger and battery, supposedly new.  It worked only once and then the "NEW"  battery went completely dead.  The battery that came with the new swivel sweeper still works.  When I contacted Amazon I was told that because I had received the replacement 34 days ago, that exceeded the 30 day warranty.  This is the first time in years of dealing with Amazon that they have not stood behind a defective product and allow a seller to sell old defective merchandise as new.  If you ignore this and other similar warnings and take a chance, be sure you use it and recharge it a couple of times as soon as you can so that if it dies you can get your money back within the first 30 days.
