I am enjoying my new fitness tracker from Polar Electro INC. The device is very reliable and gives me accurate data. The heart rate monitor works flawlessly and the battery life is impressive. The device is also water-resistant, allowing me to use it during swimming. The only downside is that the strap could be more durable. Overall, I am satisfied with my purchase and would recommend it.
