A:AnswerWhen i went into bestbuy they had a measurement bar on the counter. My wrist fit closely to the bar that marked small. It is the size I bought and I use the third hole down on the band. I don’t know my wrist measurements but the small works great for me.
A:AnswerThe charge 2 vibration is pretty strong. I like it better than the notifications of my older model Fitbit. I didn't have the aria I had a charge.
A:AnswerNo but there is a screen protector I found that is working well for me that was $15 right by where they sell the Fitbit in store. I had the tiniest scratch and now can't even tell.
