I purchased a Fitbit Charge after my Jawbone stopped working. The Fitbit is far superior to the Jawbone. The band and toughness are very important to me. Fitbit combined with Amazon is the way to go in my opinion.
I purchases an UP 24 fitness band for nearly $80. Lasted four months and two weeks and fell apart. The Jawbone company said it was not their fault and Groupon said after 14 day they took no responsibility. I could have paid $30 more and had a warranty. Do not buy items such as this on GROUPON!
