General information about our shipping
Nice bit of kit, and seems to provide good numbers. My only problem was pairing with Garmin Forerunner 310xt - it won't work properly when worn on the wrist, rather it has to be fixed to left handlebar (weak Ant+ chip in 310xt).
So neat and easy to fit. Reads similar to my other power meters on the turbo and more expensive one on my TT bike.Very cool.
Good product. Ten minutes to fit, easy to pair with Garmin 500. Power data seems to be accurate as similar readings to my Quarq. Battery died after one ride BUT I have been experiencing battery failures in other power meters. Seems to be storing them in cold conditions that does it. Just pop the battery out after a ride and no issues. Recommended - good value and neat power meter. Great service from Merlin.
