I bought this for my stopwatch interval training, which was to last only two weeks. Unwrapped I've noticed that the stopwatch has been on. As well, a friendly staff has tested by the package, if it works. Anyway, I could not exhibit it. Great part. Then the shock. At night went the ******* thing easy going and started to beep, that I have ever unpacked without. Taken at night tired that thing out of the package and issued. The next day hung around his neck and ran off. In the dark, the thing is even not recommended, but that's been my fault when ordering. Then the sprint is unfortunately fell off my part and has lost a button. Because of nighttime beeping I have not found out what it was.
Conclusion: It has night beeped again. But then for the last time ......
