Finally a product convenient and inexpensive!

I fell for this ring because it's small and especially without belt. Any woman over with cardio knows how these belts are unpleasant.
This little product is very convenient for those like me who are occasionally and wish to monitor their pulse.

I use it quite regularly, and quanb I do not use it I put it in my pocket but at least I still have time (I often forget my watch = D).
Considering the price of a cardio with belt, I quickly converted to Cardiobague.

I am very happy.
I recommend it to people with the same casual sporty profile like me (also perfect for walkers).

Sincerely.
