The band is really great ansich but as already described no guidance when buying it. Unfortunately, I will respond to the tape allergic because the sensor or the charging gate probably nickel When I called polar find .. to find a solution if there would be probably a cover or the like, I was silent on the phone only once. When I said that I surely can not be the only one who reacted to this and I do not one before abzukleben the tape from the inside with adhesive because this is not a permanent solution meant the lady: Yes you try that! Thereupon, I said again: this is not a permanent solution ... you: you try it nevertheless times I would do only once or should I call in the production time? Um yes please. The next day she called back said there must be another solution nickel in it like Tesa does not exist. If I do not want me to try the tape back pass, if there are any problems with the dealer, shall I call it again ?!
