Fuktioniert Garmin without problems

Have a Garmin 310XT and 910XT. And the original Garmin straps are more than modest. Within a short time no longer usable.
Therefore, I once started the test with the Polar belt.
Conclusion:
no dropouts, always in function, no false readings, no more highly fluctuating ads.

Only the rubber coating around the pushbuttons must be trimmed slightly (approximately 1 mm), so that the push button from Garmin sensor gets a firm hold.
