Hello! I'm thinking of getting the UP3 through work's discount program, but I am mainly looking for the heart rate feature and sleep monitor. Can anyone tell me if the updated firmware has been released and how well it works if it has been?

I've had my Up3 for 6 weeks and gone from 2000 steps a day to 10-12k a day. I love it. I have my lazy alert set Mon-Fri 9am-7pm for every 15 minutes of inactivity and it never fails. I have had no problems. It links with MFP without any hitches. The Jawbone website shows videos of how to charge, put it on (took a while first time!) and generally make the most of it. As 'just a stepper' I can't give any information about other work outs. It records my sleep/night wakes really well as well as resting heart rate. I like the encouraging notes they send me daily.

I have it. Bought it a few days ago after reading about the improvements that were made to address some of the issues with the band at launch. I previously had the UP24 and liked it, but wanted the heart rate feature. Now that I have it, I'm not sure it's worth it and don't know if I will keep the UP3 or return it.

I have the opposite problem of everyone else it seems. Lots of comments say that their band might under-report. I believe mine over reports. I say that because I was sitting in a cab tonight with the app open and watched the step count progressively increase in my ride home. All in all while in the cab my band registered about 300 steps!
