i just bought a logitech mx1000 laser mouse a week ago & after using it for 6 days, the battery was drained out & it was good considering my heavy use. anyway, i put the mouse in the cradle & it started charging right away it took about 4 hours & it still didn't fully charge so i took it out & immediately noticed that it's REALLY hot in the battery area. so i put it down on my desk & started using it & it was working like a charm. next day i turned on my pc & the mouse was dead.....as if the battery was drained out again so i put it in the cradle & after 5 sec. of charging it was flashing red ...... no matter what i do it just doesn’t charge & doesn’t even light up when i take it out of the cradle....just keep flashing red anytime it's in the charger. very disappointed since i thought it was a quality product.... & to make the deal even sweeter it was imported from the UK for me so returning it for RMA will cost me about $120 in my country coooool Logitech
