Design And Build Quality

Like Haylou RS4 and in the footsteps of the Apple Watch, The Haylou RS4 Plus smartwatch has a square design that looks very clean and elegant in black suitable for both men and women, and features a smooth 2D curved glass in a metal frame with a brushed finish, giving it the look of an expensive watch, and it really is, And it has one button that turns on-off and the menu. Overall, the body is slim and light and made of high-quality aluminum alloy with 45mm large size and 10.4mm thickness, which makes it lightweight at just 55g and therefore comfortable on the wrist.

If you look at the back, there’s nothing out of the ordinary, just a plastic cover with magnetic charging pins and a sensor.

The quick-release strap is made of silicone with magnetic closure, lightweight, and comfortable on your wrist for long-lasting use. You can use any 20mm strap because it’s removable and available in black, silver, and gold color but you can buy another strap from metal or leather separately.

Display Screen

The screen in Haylou RS4 Plus Smartwatch is my favorite type and one of the strengths of this smartwatch, Unlike other budget smartwatches that contain a TFT panel, the RS4 Plus has an AMOLED display with 1.78 inches, which makes it the largest among all the budget smartwatches with AMOLED screen reviewed so far. The glass is 2.5D curved to display better content and details, and because it has a resolution of 368*448 pixels with a 60Hz high refresh rate continues to optimize the user experience, which is rarely for round smartwatches that can be currently available and this makes it more attractive in the hand.

Definitely, it’s one of the best screens in a budget smartwatch in terms of size and resolution, even the sharpness of colors and brightness are so good, especially when you wear them in the sunlight you won’t be alarmed by them. And for the first time, the Always-on Display feature works and can be activated from the settings, and it wakes up the screen.

In fact, the reason makes this type of screen my favorite is that large and takes over most of the interface, and with narrow sides, and this is only found in smartwatches with higher costs. This is in contrast to other inexpensive smartwatches that contain a touch screen, which comes in the middle of the screen and has rather wide sides.

Haylou RS4 Plus Watch Faces

If you are tired of the system default dial background, Haylou RS4 Plus Smartwatch has 10 pre-installed watch faces, you can switch between them easily by long pressing on the home screen or via the Haylou Fun app for more watch faces with over 100 online watch faces are available for download with customization capabilities for a variety of colors, retro, analog, 3D, and digital faces or your own photos as a watch face background or any wallpaper.

Dustproof & Waterproof

Although it has a good sensor that is more accurate than other sensors, this does not mean that the measurements provided by this smartwatch are completely accurate, as most of them are largely unreliable because it’s not a medical instrument, but it makes you very aware of your health and physical performance. unfortunately, this is often the case with watches in this price range.
