I have a new heart rate monitor required and had the years before becoming a product of the brand, which have made it popular as the first such products on the market. Unfortunately, these products for the performance offered / functions over the years have been too expensive. Even the simplest model of this manufacturer is more expensive than the model from Beurer, has more features, meets my needs (eg accurate pulse measurement, timekeeping, alarm) outstanding. The design of the clock like it very much, and the side buttons on the device are easy to operate. The decisive reason for "ours" the two-color LED are ads that show me at once (if enabled) if I'm in the normal or high heart rate zone and this (but this is also possible) (red or green) without annoying beeping. Another reason for choosing this model is the simple exchange of the batteries in the included chest strap and the clock. What should be mentioned is the quality storage box made of sturdy plastic and the foam therein to keep the clock and the chest strap and the free supplied bracket (gummy plastic) for the bicycle handlebar (which is very convenient). The clock and the belt were worn since the purchase (for about 2 months) very often and I have never regretted buying this model in any way. I think that this product has an excellent price / performance ratio and can with a clear conscience.
