What owners say about the Haylou RS3

Based on 73 owners sharing their experience in online comments

19%positive37%mixed44%negative

Owners praise the vivid AMOLED screen and long battery life, while GPS failures and app problems frustrate many.

What owners dislike

  • GPS often takes about 4 to 6 minutes to find a signal, sometimes never connects, and can still be slow or unreliable after it locks.14
  • The Haylou Fun companion app disconnects often, fails to register workouts or syncs them days late, and some users cannot finish sign-in or pair the watch.9
  • Owners say the workout route map does not appear in the Haylou Fun app or does not export after a GPS run, showing only stats.7
  • Watch face choice is limited, with few faces in the official app, and some faces appear blurry or fail to install on the watch.4
  • The interface lags, and owners say the watch wakes by itself when moved and the sleep-mode button does not work as expected.4
  • The screen sometimes stops responding to touch, and after a reset some watches will not power on or connect and show only a QR code.4
  • Owners report repeated notification vibrations that cannot be turned off from the watch, and some describe phantom vibration alerts.3
  • Some watches fail to charge or power on, including units that show no charging indicator, and one restart left the watch unable to start.3
