Geonute HRM
Easy to use.
Used for 2 to 8 weeks
Does the job I needed it to do has the time on it and a rubber strap which is appropriate when I wear it for workouts. Other functions Good though I rarely use them.
Good Value
Used for 3 to 6 months
I have a very expensive Heart Rate watch, as I run ultra-marathons and train using heart rate. I wanted something more simple, and less expensive, for my girlfriend - she wanted to train to heat rate, but didn't need any other complex data fields or GPS. This was perfect - easy to use, large numbers and slim fit. It seems accurate and is certainly good value for money.
