The great design of the clock has led me to buy - would have been better to pay attention to the recessions. The end of September came the clock equal to the big marathon use - after exactly 3:30 hours left me the clock - the battery is completely empty, although previously loaded! Have you yet still several opportunities given for smaller runs all great except for the handling with the bracelet a bit cumbersome. Today a run over 3 hours gave her the rest back battery problems - will return as the clock definitely unusable and buy me a better model - a pity. ************** 21 May 2015 The clock was now - easily exchanged - after a telephone conversation with the customer service! Bin so now run for more than 3 hours and the battery is still half full on! Problem should be solved. Many thanks to the Lord of the customer service!
