Possessed before purchasing a PM 62. Unfortunately, over time, about 3 years, defective. Occasionally had I workout when no pulse rate display, bzw.zu beginning of the training it took was a very long time to rocketing pulse appears, despite "gel insert". Since I was mostly pleased I had decided me a replacement zuzulegen PM 62 1. purchase beginning in December 2013 - despite wearing long hours - No pulse reading. Have downloaded at Beurer the manual to be sure that I have no maloperation do. The "Mini Guide description in English" was not helpful. No Success.
2. Complaints in the old year. Clock was exchanged. Same problem of Ersatzuhr- No pulse reading. Renewed complaint with a request for credit. Credit was made quickly.
The problem of lack of pulse rate indicator has been on a number of assessments shown. Did this not so rated. In such circumstances, do not recommend buying the PM 62.
In the meantime I bought the PM 70 Beurer. No Problem.
