The one thing letting this feature-packed heart monitor down is its instruction booklet, which makes it hard to understand how to programme it for use.
The watch itself looks and feels good quality and reminds me a lot of an old Nike sports watch I once had. It tells the time and date and features a light, stopwatch and countdown timer. All off these are easy enough to navigate and use - its the main function that is a bit annoying.
The heart rate monitor does works and that too has some nifty features, like and optimum heart rate zone, which you can personalise to suit yourself. Work out your perfect zone for burning calories (this is easy enough to do using your age and a simple equation given to you in the instruction booklet) and you can enter it into the watch... This is where things get a bit tricky.
The instruction to do this are terrible; with things in an illogical order and ill thought out instructions. It makes it a real chore. However, keep at it and your will eventually get your head round it.
One you have your optimum heart rate zone entered, you can then set the watch up to beep when you exceed or drop below you ideal heart rate, thus ensuring an efficient workout.
It also tells you the percentage of your maximum workout rate too, so you'll know just how hard your pushing yourself. The chest strap works well, transmitting data to the watch, but it can start to slip down your chest a bit when you get sweaty and you're moving about.
Overtall, I'm happy with the device. It does what's asked of it, it's just it was about 5 or 6 workouts before I figured it all out... I think I've got it now, but I'm not 100% sure I'd be able to set it up again when the batteries run out, so I won't be throwing away the instructions - even though they are very poorly written.
