Optical: the clock like it very much outside and fits perfectly with small wrists. Since only two buttons are attached will not affect the clock lumpy or large. The time and date display is large and legible. The included chest belt seems quite large and is in the closest setting almost too far. He leaves after wearing slight bruising but does not feel uncomfortable when worn on. However, I have not tested it as he runs. Handling the supplied instructions is a little too short and covers only the basic settings with the Manual CD I can not do anything because I do not have a laptop drive. However, I could find more information quickly on the Internet. The User setting can be done without guidance, training mode, I had a little but try to find your way quickly. Conclusion: For amateur athletes and beginners super useful! Appearance: 5 stars, price / performance: 5 stars, Handling: 4 stars, chest strap: 3 stars
