I wanted to pass me a cardio belt. Even if I found the price a little expensive I decided on the basis of several positive reviews buy this watch. AND what a disappointment well. Cardio disconnects all the time. various firmwares are doing nothing. I am reduced to the couple to a H6 thriller. By GPS against work properly. mYsports the site is really basic and I almost forgot .... no ..... app for Android is expected in September ... My advice ... wait September. I'm sure other expensive and more reliable and complete moiuns products will be out by then.
