What owners say about the Kieslect KR2

Based on 56 owners sharing their experience in online comments

16%positive11%mixed73%negative

Owners like the stylish design and value, but frequent connection, notification, and reliability problems overshadow them.

What owners dislike

  • Several owners report the watch screen going dark or not showing after a few days or months, even though the phone still sees the watch and it shows full charge.10
  • Notifications often fail to arrive or show the wrong content, such as the first Telegram message instead of the newest, or a saved contact's name missing on incoming calls.8
  • Bluetooth to the phone drops repeatedly during the day, even when the phone is nearby, and some owners say it disconnects at only about 4 metres.6
  • Owners report software bugs, and some say a recent update broke the watch, removed Arabic language support, or left it unable to turn on.6
  • Some owners say heart rate readings are not accurate, and one reports step counts still rising while driving in a car.4
  • Some owners say the screen stopped displaying or looks poor, and one says it failed after only two months of use.4
  • Battery life is short for some owners; one reports the watch losing around 7% overnight while idle, and another says it lasts less than three days.3
  • Owners find the watch has too few standalone features: no built-in music storage, no SIM or calling, and limited apps.3
  • Owners say warranty and repair service is hard to get, and one says nobody will repair the watch after ten months.3
  • Owners say the oleophobic coating wears off quickly and the glass is not sapphire, so it scratches easily from door frames and edges.3

  • Vibrant 1.43-inch AMOLED display with high contrast and smooth 60 FPS refresh rate
  • Excellent value for money, often cited as a solid budget everyday watch
  • Reliable battery life lasting roughly 5-7 days under typical use

  • Limited interaction with notifications; users cannot reply directly from the watch
  • IP68 water resistance is not suitable for swimming or high-impact water sports
  • Occasional software glitches such as inaccurate step counting or display issues with notifications
  • Lack of automatic brightness control and limited Always-On Display (AoD) customization

Verdict

The Kieslect KR2 is a performance-oriented smartwatch featuring a 1.43-inch AMOLED display with a 466x466 resolution, 1000 nits peak brightness, and a fluid 60Hz refresh rate powered by a 2.5D GPU. Its unique dual-core architecture (240MHz high CPU and 96MHz low CPU) balances speed with efficiency, delivering a 30% reduction in power consumption and supporting a 360mAh battery that lasts up to 7 days. Key characteristics include an IP68 water resistance rating, a triple digital crown interface, one-step Bluetooth 5.3 calling, and advanced biometric sensors that claim 40% higher heart rate accuracy. Main pros include its premium metal build, exceptionally smooth UI animations, Always-On Display (AOD) support, and a comprehensive suite of over 100 sports modes and health monitoring tools. However, notable cons include the lack of built-in GPS, limited notification interaction beyond reading messages, and an IP68 rating that is not recommended for intense swimming or diving.
