Apologies if this ends up not being coherent. I'm not feeling the greatest right now (have a sinus and ear infection and just generally feel like yuck), but I have the time and interest to write this now, so, here goes!
My husband got me the Fitbit One for my birthday! It arrived Thursday evening. I've been using it since then, and I'm pretty pleased with it so far.
It's tiny! And the clip stays VERY firmly attached to my pants. Those were some of my biggest gripes with my previous pedometers. They were pretty big, and kept falling off. Plus, where they needed to be placed meant there was always a weird bulge under my shirt, and when ever I sat down, or heck! just moved around, it was getting knocked off my waistband. That led to the demise of my last one, as it didn't have a tether and got dropped on the floor one to many times.
With the fitbit, I can clip it to the side of my pants, rather than in the front. Which solves the knocking off problem. Though, it holds on so much better it probably wouldn't fall off anyway. The fact that it's so small means it makes a much smaller bump under my shirt, and since it's on the side, it's harder to notice.
It seems to be more accurate, and also appears to be able to tell the difference between me walking and riding in a car. I don't think it requires 10 steps to start counting, either, so I assume it will pick up even short movements.
I don't have to do anything besides sit at my computer to log how much I've walked for the day, and then it gets uploaded to Spark. That's super convenient. I haven't messed around with the Fitbit dashboard that much, but it seems pretty cool as well. However, since it duplicates Spark, I probably won't do much with it.
The sleep tracking feature is interesting. I have no idea how well it actually tracks how much I'm asleep for, but it is pretty handy having a record of when I went to bed and when I got up.
I don't know how I feel about the alarm yet. I will give it a week before I make up my mind. It did wake me up this morning. At least, sort of. I don't like that the only snooze option is to ignore it. I suspect that will pretty quickly lead to just sleeping through it altogether.
Overall, I am very pleased with it and glad I got it. I think it will be a big help to me, because having a thing tracking how much I move around has proved very good at getting me moving in the past.
Edit: I have given up on the silent alarm. It just doesn't wake me up. Halfway, just enough to turn it off, seems to be the best it can do. Oh well. Wasn't a feature I was particularly excited about anyway.
