Pros:
Easy plug and play charger, light turns green after being charged.
Cons:
Take a long time to charge high capacity batteries. The charges at 5mA only which can take a long time to charge.
Other:
If you serious about charng li-ion batteries buy this. http://www.dealextreme.com/details.dx/sku.15225 get 12-15v power supply rated 5AMP or higher. Build a battery holder for your battery type. Tell the charger you charging li-ion enter the capacity and go. your cell will be charged in 1hr.
Bottomline:
Good charger if you can leave it, but I know enough to get in trouble. :)
