i sent my quarq back on a thursday. had it back the following wednesday. the customer serice was excellent from start to finish.

they replaced the electronics pod and snugged up a loose chainring bolt. only two rides since due to a short vaca and the weather, but all seems good. it sync'ed up fast & calibration was at 74. that function was typically returning a number around 350. no dropouts or odd readings. the unit actually appears to go into sleep mode now when idle for 10 minutes. i determined this durning a 20 minute flat tire change. i dont think it did before and i was going through batteries. later.
