COROS Heart Rate Sensor Armband - Almost New

This is a COROS heart rate sensor.
After purchasing it, I used it for about 15 minutes once and immediately switched to another sensor. Therefore, there is almost no sign of use, but please refrain from purchasing if you are overly sensitive. Please check the photos for the condition.

Includes a dedicated charging cable, original box, and instruction manual.

Sleek Design & Comfort
The COROS heart rate sensor uses soft band fabric. It's easier to attach to your forearm or upper arm than a chest heart rate sensor. Its slim design prevents snagging on clothing or gym equipment, offering a level of comfort that lets you forget you're wearing it and focus on your workout.

Adjustable Fit
You can adjust the fit to the optimal position by sliding the buckle. It's a hook-and-loop fastener type, so it's easy to remove for washing.

Latest Sensor
The latest multi-channel optical heart rate sensor achieves highly accurate heart rate measurement. The scratch-resistant and protected sensor, housed in a sleek body, provides reliable and accurate heart rate data daily.

Excellent Band
High-accuracy measurement functions by securely fixing the optical heart rate sensor to the skin. The COROS band is designed to ensure the sensor fits snugly against your arm, preventing external light from entering.

Amazing Battery Life
The COROS heart rate sensor offers 38 hours of operation on a single full charge and can remain powered off for 100 days when not in use.
