Haylou RS4 Plus

One of the main features of Haylou smartwatches is a high-quality 1.78-inch AMOLED display with touch controls. This screen is characterized by high image detail and has a resolution of 448x368 pixels, as well as a pixel density of 326 ppi, which is a record in this price category. In addition, the device boasts a refresh rate of 60 Hz and more than 100 different watch faces.

Haylou RS4 Plus stands out from its predecessor Haylou RS4 with a magnetic clasp that replaces the traditional buckle. The number of sports modes has increased significantly and now stands at more than 100, up from 12 on the previous model. During exercise, the watch can record heart rate, estimated calorie consumption, distance traveled, number of steps, and other activity indicators.

The housing of Haylou RS4 Plus is made of metal and has IP68 protection, which provides reliable protection against dust and water. However, it is not recommended to use them in the shower or in the pool.

The watch can measure the pulse not only during sports activities, but also around the clock. They can also measure blood oxygen levels, stress indicators, track sleep and keep a women's calendar. In addition, they can complement the smartphone by alerting you to calls, SMS and other notifications. In normal mode, Haylou RS4 Plus can work up to 10 days without recharging.

The device does not have a GPS module, so runners will need to pair with a smartphone to navigate and accurately determine the distance. All in all, Haylou RS4 Plus is an interesting and handy gadget with a great screen, good functionality and long battery life for its price.
