Hands-on review · Calling smartwatch
Verdict
The Kieslect KS2 is a light, long-lasting calling watch that ran 17 days in testing, but it cannot run third-party apps or track routes on its own.

Third-party reviews

What we like about Kieslect KS2

  • High-quality 2.01-inch AMOLED display with vibrant colors and 1000 nits peak brightness for excellent outdoor visibility.
  • Exceptional battery life, lasting up to 9 days in typical use and up to 40 days in power-saving mode.
  • Fluid user interface performance supported by 'Dual Core' technology and a 60 FPS refresh rate.
  • Comprehensive health tracking features, including a one-tap test for heart rate, SpO2, and stress levels.
  • Convenient Bluetooth calling functionality with a built-in speaker and microphone.
  • Lightweight and comfortable design with an aluminum frame and support for standard 22mm interchangeable straps.

What we don't like about Kieslect KS2

  • Poor companion app experience, with users describing the 'KS OS' or 'Kstyle OS' as buggy, difficult to navigate, and unreliable for notification management.
  • Hardware durability concerns, including reports of the rotating digital crown failing shortly after purchase.
  • Lack of advanced connectivity features such as built-in GPS, NFC for payments, and eSIM support.
  • Inconsistent notification system that sometimes only displays icons without message content.
  • No support for third-party applications, limiting the watch to pre-installed tools.
  • Limited onboard memory for watch faces, allowing only a few to be stored at once.
  • Occasional connectivity instability and syncing issues between the watch and smartphone.

Verdict

The Kieslect KS2 is a performance-oriented smartwatch featuring a 2.01-inch FHD AMOLED display with 1000 nits brightness and a 60Hz refresh rate, powered by a dual-core chipset that reduces energy consumption by 30%. Key specifications include Bluetooth 5.3 for stable calling, 3ATM water resistance, a 300mAh battery offering up to 9 days of typical use, and advanced biometric sensors for 24/7 heart rate, SpO2, and stress monitoring. Its main pros are the fluid user interface driven by a 2.5D GPU, one-step pairing for calls, and support for over 100 sports modes with smart recognition for six common activities. However, notable cons include the lack of built-in GPS, no NFC support for contactless payments, and a plastic back cover that some users find less premium than high-end alternatives.
