JUNK!!  Do not buy.  If you already own, NEVER move it...
In the 13th month of ownership, the warranty and original battery simultaneously expired.  Of course, the product and App didn't initially state that it had a low battery.  On the contrary, it just started miscalculating weight - falsely overstating my weight at a progressive rate of 3 lbs a week.  After a few weeks and total anxiety about gaining 15 lbs yet all my clothes still fitting fine, I decided to replace the battery.  At that point, it couldn't reconnect to my wifi.  After repeated removal of the battery and resetting the scale and my wifi password, it finally reconnected to the wifi.  However, at that point, when I attempted to use the scale, the screen would indicate &#34;THINKING...  ERR.&#34;  I called Fitbit customer service for help.  They told me that since the problems started after the 12 month warranty expired, they would not cover any repair under warranty.  They further told me that because I moved the scale around too much (most likely from flipping the product over to access the battery and reset button), I disrupted the sensor calibration.  The internal parts that operate this sensor calibration are non-serviceable, so the device is now a paperweight...  This is a known issue by Fitbit.  Just do a web search on Aria Thinking ERR and you will see a multitude of unhappy product owners.  The Fitbit customer service person even had the nerve to suggest that I upgrade to the Aria II scale since I had a problem with this one.  Of course, they offered zero compensation to cover this upgrade cost...  Don't buy this garbage product!  Don't trust Fitbit.  They don't stand behind their products, they put junk into the marketplace, they know it's junk, and they don't take ownership of the problems they create for clients.  I would rate this as the worst customer service experience I've had in consumer products for as long as I can remember.<br /><br />UPDATE - June 2019.  I decided that after 18 months, I was going to try again to get this scale to work.  Put in new batteries and connected it to the network / fitbit, with the hope that it would load a firmware update and fix itself... wishful thinking.  I reached out to fitbit to see if there was a firmware update or some other resolution.  Surely, if they had thousands of complaints on their fitbit community forum, they must have realized that they needed to take some accountability for this product.  Again, I got the same nonsense response.  Since the problems happened after 1 year warranty expired, there is nothing they can do.  I asked for a suggestion on a quality scale and they said the Aria 2 was greatly improved over the original - the issues with the 1st generation were resolved in the manufacture of the 2nd.  So... I asked if they clearly knew there were defects in the original, why didn't they reach out to customers during their warranty periods to ask if they would test for the defect (many reviews showing the same fail said it happened after the first battery change).  This question seemed to freeze the customer service person I contacted.  They had no answer on why a company claiming to be focused on customer service and care would do such an unscrupulous act.  At this point, she said there was nothing she could do, so she transferred me to a supervisor.  The supervisor hear this same question and said... "let me review the entire case file and repair claim and see if we can reach a final resolution."  The conclusion of this call was unfortunate.  This time, they offered to sell me a replacement Aria 2 scale with "free shipping" and/or a 3 month trial membership of Fitbit Coach... What a joke.  They sold me a lousy product that they knew was defective at the time I bought it (I purchased it Dec 2016 after the Aria 2 was already on the market), they chose not to notify me during the 12-month warranty period of the potential product failure if batteries are replaced, then, after I got the product failure in month 13, they said, "too bad, you reported this problem to us after your warranty has expired, there is nothing we can do."  I ask you... is this a company you would want to do business with?
