"Its massive battery and rugged shell hide a very basic and questionable set of smart features."
The 800mAh battery is genuinely large for a smartwatch, but the '100-day' life is a marketing figure achieved by crippling its smart features. Expect a week or two of actual smart use, not three months.
This is for a buyer who prioritizes battery duration above all else and only needs basic notifications and Bluetooth call answering. If you need a watch that looks tough and can survive a long time away from a charger, it warrants consideration.
Anyone seeking accurate fitness data, a polished software experience, or meaningful integration with major health platforms should skip this. For a similar price, brands like Amazfit offer proven hardware and vastly better software, albeit with smaller batteries.
