I have a new Polar S720i, and have been using it on my road bike for a few weeks. The thing works fairly well, although a LOT of interference problems, but that is fairly standard.
My big problem is that it often has this huge rainbow pattern on the LCD screen behind the digits - ie, in the LCD screen itself. On bad days, this can make the screen almost unreadable. Some days it works just fine. The problem only occurs outside - so it somehow or other does depend on or react to light from the sun.
Polar says that this is normal, and is a function of the manufacturing process. I frankly completely disbelieved this - they would not sell a single S720i if that was the case - it is unreadable! And no other LCD screen I have has ever had this effect, so it is not a general LCD problem.
I finally sent the thing back to our local agent here in Australia, and they were truly great. Very professional and super fast. They actually changed the whole LCD screen for me the same day, basically.
But unfortunately, the rainbow effect is still there. It is a totally different pattern this time, but the problem is still there. So I am beginning to think that Polar might be right after all - it is a manufacturing problem.
Does any other S720i user have this problem? I did see a post from another user where he noticed the effect, but as it was only minor, he could tolerate it.
I have used a S710 for a few weeks, and that was perfectly ok - no problems at all.
