That's the model I have, and I love it. I've recently started wearing mine again, and every night I record my steps at Walker Tracker
It's fun to use that site because it keeps track of miles walked, step averages, etc. etc. etc.
Even though I haven't lost weight yet, I know I'm improving my condition because it's getting a bit easier to increase my daily steps. I've had to start all over again, so I aim for a minimum of 5000 a day right now, and find it quite easy to get at least 6000 most days. I'm working my way up to at least 10,000.
By the way, there's no charge for Walker Tracker, and I'm not connected to it in any way. I just love keeping track of numbers.
I think you'll enjoy the Omron if you get one.
