“The Band 2 has been wiped completely from Microsoft’s online store and is no longer available from Best Buy either,” technology website The Verge reported on Tuesday.
Consumers can still buy it from Amazon through its remaining inventory.
The team behind the “Band” was recently dissolved and the company has also removed the device’s software development kit that allows apps to be created for the device from its site.
Microsoft, however, will still support existing “Band 2” owners.
The device was criticised for its uncomfortable design. Microsoft introduced a second-generation model with added features last year but it also carried forward many of the original’s flaws, the report added.
