over all good product good service as well, delivery time frame acceptable. I have only two things that I am not happy with product and it is the sensor h7 strap, it is not really good at all, something is uncomfortable and difficult to find a position to stay firm and to do not hurt you. it allays blend whiile using it. the other thing is the gps of this product is terrible, probable because I am using it more indoor than outdoor, but even that it is terrible. regards.
