It also has two prominent buttons on the right side that work on power and back, and although it is a budget smartwatch, you will notice that the manufacturing quality is high and even the design was great.

The RT LS05S smartwatch features a lightweight and comfortable sport silicone strap on your wrist for long-lasting use. You can use any 22 mm belt because it is removable and appears to be available in black color only, but you can purchase other colored belts separately.

Display Screen:

The screen itself is common in other cheap watches, it is a 1.28 inch TFT screen which is considered rather small and even with a resolution of 240 * 240 pixels, it’s very normal although the sharpness of the colors is acceptable, but when you wear it under the sunlight there is some inconvenience.

haylou-ls05s-rt-smartwatch-review

The brightness can be changed to get better contrast under the sun, in fact, what is annoying about such smartwatches is that the touch screen comes in the middle of the screen and has slightly wide sides.

Watch faces:

Haylou RT LS05S has some different pre-installed watch faces, and you can switch between them easily by long-pressing the home screen or via the Haylou Fun app which has many watches faces with customization capabilities for a variety of color, retro, analog, and digital faces available or you can even use your own photos as a watch face background. And with the wrist-raised feature to wake up the screen, that would be great.

Waterproof:

Haylou RT LS05S is IP68 water-resistant smartwatch, which means you can wear it while washing hands or on rainy days, although the watch is not approved for swimming but is good wearable for activities, so I do not recommend swimming or exposing it to hot water or saltwater to avoid any long or short term damage. And its preferable to dry the watch after immersing it in water and before operating it, in order for it to stay with you for as long as possible.

Under the hood:

The company did not disclose the type of chip used in the Haylou RT LS05S, however, the response of the smartwatch was fast and without any restrictions, and for your health, this device contains a heart rate sensor and an acceleration sensor, so that this device manages your movement at every moment and takes good care of you The whole day.

However, it does not have its own GPS sensor which means you will always have to use it with a smartphone to get your location.
