3 / 5

After 3 disappointments, I still hope I bought a good heart rate monitor.

- Raf, 24 February, 2025

I have used it 3 times now and every time I have the same problem.When I cycle at a good pace, my heart rate meter indicates +/- 120, which is normal for me.If I increase my effort seriously, e.g. when going up a mountain, my heart rate meter drops to +/- 35 and sometimes even to 0.Strange but true, when I exert myself, my heart rate drops, at least this is what my Garmin indicates.If my son puts the heart rate meter on, it works normally.

Pros & Cons

good price
I do not find the strap closing very practical
