Bests & Worsts Reviews from Amazon

I purchased UP by Jawbone on February 27, 2013. I read the reviews about the band not working properly after a short period of time as well as the reviews raving about how great the band is at tracking activity and sleep. I decided to purchase the band based on my very positive past experience with Jawbone's products (I own a Jambox, which I highly recommend). On April 9, 2013 the band began to act funny, not holding a charge, and while I think about it for the past week it has not been recording sleep properly which I put it down to my own forgetfulness by not putting the band in sleep mode. Today, April 10, 2013 the band is dead, I charged it and did a soft reboot of the band and nothing. I should have given more weight to the reviews about the band not working properly since there were so many of them and upon reflection should have bought a Fitbit or Nike Fuel. I would like to return the UP band and get a refund but Amazon will only accept returns within 30 days and I think I have owned the band for 40 days. It's a shame because I really liked the UP band while it worked, it is a real fitness motivator. 5/9/2013 UPDATE: I received a replacement band from Jawbone and it has been working fine, I have been using it for the past 14 days and I do like it, the true test will be if it works in 6 months or a year. I will update and revise my rating if the product continues to work. 6/13/2013 UPDATE: I received a replacement band on 4/27 so it is about 48 days and the band seems to be working. I am happy about that, because as I stated earlier I do like the band, I just did not like that it died after 40 days. I am increasing my star rating because as long as the band keeps working I think it's a good product, although I would not be comfortable recommending it to anyone until I am certain that the band will work for a longer period of time. 6/15/2013 UPDATE: The replacement band stopped working. I am finished with this product and resent that I paid to be a beta tester. I will try to get my money back.
