Tudia EVA Empty Case for Heart Rate Monitor with Chest Strap Compatible with Polar H10

Hay que enrollar mucho la cinta y apenas cierra con la cinta y el sensor adentro. Pero es de buena calidaf

The image shows that the heart rate sensor is about the same size as the case and fits snuggly in the mesh pocket. As seen in my attached photo, the sensor isn't the same size as the mesh. Otherwise, it works great. The photos show that the sensor doesn't fit as showing in the product image.With the strap in the case, it feels like the zipper's material is pulled tight, but it closes with no problems.I actually enjoy using this product with my HR Strap and sensor. I just make sure the strap is dry before I store it.
