I recently purchased an FS Labs 5-in-1 battery charger from Amazon.  There are mixed reviews, but it seems that buyers are very happy with the purchase.  Before I start using it, does anyone have any experience with it?  And is there any concern about harming my batteries in the long term or warranty issues?  TIA.
