I absolutely love this EvolutionX Cordless Mini Chopper by Cuisinart.  The directions are upfront and easy to understand.  It came out of the box about 50% charged.  It took less than an hour to fully charge.  The chopper has blue led indicator lights to let you know the battery capacity.  This makes chopping and/or grinding effortless.  I was able to chop up and onion with no issues at all.   

The lid must be closed, and locked into place in order for the chopper to work.  I appreciate added safety feature as the blades are sharp.  This mini chopper is more powerful than my full size food processor..  Its durable, and well made.  The mini chopper far exceeded my expectations.
