I got a fitbit about a month or so ago. I really, really like it! I'd been looking for a good pedometer. I like tracking my food and weight online. And I love to see how many calories I've burned. Well, this has given me all that and more.
It's super small so it fits in your pocket or clips to your bra without any problem. It's easy and accurate! It even tracks your sleep! Seriously, you put it on a wristband overnight and it knows when you fall asleep, how many times you woke up and then gives you a number for how long you were actually asleep. It's kinda eerie but extremely accurate! Plus, it's super comfortable to wear so it's not like hooking up to a huge contraption.
The only drawback is that it IS small and I'm always afraid I'm going to lose it. I have a good routine with it now so I'm not as fearful anymore.
It is a bit spendy, it's $99 on fitbit.com. I debated a long time over this, I don't have money to burn, that's for sure. After reading several reviews and committing that I would actually USE it, I bought it. And I'm glad I did. Now my husband wants one. He wants one more as a toy though than a fitness tool. I thought about changing my profile to his stats but that would mess things up for me so phooey on him. I'm keeping it. :-)
You are able to use it for social networking and you can find friends and compare numbers. I would LOVE this as I think it would keep me going stronger to know that someone else was watching my stats and knowing how many steps I take a day. However, I have yet to find anyone who uses theirs regularly. If you are using one, I would love to "friend" you on fitbit. :-)
