vibrating wrist watch alarm clock - great concept, I had high hopes for this item as I typically sleep through my Fitbit alarm. it may be operator error but this item fell short of my expectations. I found it difficult to set the alarm, the display is hard to read and apparently according to the instructions there are multiple settings for strength of alarm depending on how deeply you sleep and it appears that it also tracks steps, I was not able to figure out how to change the vibration setting or utilize the step function. the band itself is comfortable to wear however the clip secure very well in my opinion. you have to remove the watch part from the band and plug it into a USB to charge, I do like that part
