In a move to placate dissatisfied customers, Jawbone is offering refunds on their highly hyped UP wristbands, with no questions asked. The devices are supposed to monitor sleep and exercise patterns of the wearer, but many users reported problems with battery life and its ability to sync with phones and computers.

Starting today, any UP customer can log on to the Jawbone site and file for a refund. You don’t even have to send the UP band back, and Jawbone will send a check for the purchase price of $99.99, says PCMag.com.

Jawbone is known for their Bluetooth headsets, and had high hopes for the UP bands, which hit the market in November. Due to the performance issues, they won’t produce any more of the wristbands, but will keep updating their apps for those who continue to use them.

“While many of you continue to enjoy the UP experience, we know that some of you have experienced issues with your UP band,” Jawbone chief executive Hosain Rahman wrote in a blog post. “Given our commitment to delivering the highest quality products, this is unacceptable and you have our deepest apologies.”
