I bought it purposefully to record my running sessions. So do not wear it except during sports. This means the battery lasts a long time. He does registration very well. Polar records cadence differently (actual cadence / 2). So if your cadence is 180, the Polar Pacer registers it as 90. Very confusing and illogical, but after digging deep into the manual I figured it out. That said, the registration still appears to be quite accurate after I manually count and keep my count next to the registration.
An XL strap is also included. Unfortunately with an incorrectly mounted pin so it does not fit. Must be a factory error.
Screen is easy to read, four fields per screen and multiple screens can be set.
The Polar app is less intuitive. Programming a running schedule is not convenient and cannot be edited on the mobile, only in the browser. It's a matter of getting used to it. Polar keeps the data private, and you must agree to share that data in order to use all the features you paid for. That is not something you know before you buy such a watch, but only when you register and create an account.
For now quite happy with this watch, it does what it's supposed to do if you only use it for running.
