I requested this to use not as a fashion accessory but for its intended purpose and so far, it does the job well.  Weighing nearly 1# with a band sized to fit a small tree trunk, it is not for the weak-armed.  The functions are easy to use and have been accurate.  It offers more than the casual user would need, particularly now that phone apps will take care of the same measurements but for underwater or other tasks where a phone is not practical, this is a reasonably priced alternative.
