    Verdict

    The Fire-Boltt Grenade is a rugged, affordable smartwatch featuring a 1.39-inch HD display with 360x360 pixel resolution and a sturdy metal body with shockproof protection. Key specifications include Bluetooth calling with a built-in speaker and microphone, a 350mAh battery offering up to 7 days of standard use, and support for 123 sports modes along with health monitoring for SpO2, heart rate, and sleep. Its main pros are the premium build quality, clear display, and reliable Bluetooth connectivity; however, cons include limited outdoor screen visibility due to its LCD panel, a lack of built-in GPS, and significantly reduced battery life (down to approximately 2 days) when Bluetooth calling is heavily used.
