Overall, ITALK works pretty well.
I am fairly impressed with this clock.  I bought it for my Grandma who is 92.  Programming was pretty easy for me, but I knew it wouldn't be for her.  The voice recognition could use some help.  You have to repeat yourself several times.  I found it's just easier to press down on the top of clock to stop the reminder or ask it a question.  It suits it's purpose though.  It helps with the daily reminders like medications, etc.  I have already noticed that it is helping with her daily routine, so I quess it was worth the money.
