I have been working out lately and wanted to keep track on my health and monitor my heart pressure. I got this because it has phone connectivity which lets me keep track on my phone which is great as I am always on my phone. Its light weight and super portable for me to take with me where every I go. The built in battery is also great as I don't have to run around looking for batteries, I can simply plug it in and charge it. Fits comfortably In my wrist and the material is great. I have no complain. It is a bit pricy compared to the other options but with the functionality it provides, it makes up for it.
