Relatively inexpensive smartwatches have joined the 2022 Haylou brand lineup. Due to the rectangular shape and small thickness (11 mm) of the metal case, they visually have a lot in common with the Apple Watch. Also, the model is notable for a rather large 1.78-inch AMOLED screen with a resolution of 448x368 pixels and touch control. Other features of the "stuffing" include a modern Bluetooth v 5.1 module for pairing with a smartphone, an accelerometer, NFC (supports Alipay contactless payments that work only in China).

The Haylou RS4 smartwatch is able to measure the pulse, the level of oxygen in the blood, record the number of steps and the distance traveled, track sleep, notify the user about calls, messages, etc. Sports fans should be interested in 12 supported sports modes, ranging from running or cycling to rowing, basketball or football. The advantages also include a capacious battery (230 mAh), which should provide up to 10 days of autonomy in a standard use case. Among other features of the model, it is worth highlighting the presence of a rubber quick-release strap and decent water resistance parameters (IP68 class), which allow you not to be afraid of rain and do not take off your watch to wash your hands.

Inexpensive but high quality

The Chinese brand Haylou is a partner of Xiaomi and seems to have inherited one of its main principles from it - to offer quality gadgets at reasonable prices. There is no markup for marketing and the promoted name of the manufacturer, so you get a good value for money. The RS4 is a prime example of this. This is a comfortable smartwatch that frankly copies the design of the Apple Watch, but this is not a cheap Chinese clone with an assembly “on the knee”. The gadget weighs less than 50 g, is practically not felt on the wrist, has a metal case and IP68 water resistance, and the last two points are not often found in low-cost products. Although not everything is so smooth with water protection: you can wash your hands, walk in the rain and actively train with a watch on your hand, but you should not swim in them, swim and take a shower.

The device looks neat on both female and male hands. Despite the fact that a large 1.78-inch screen is installed here, the smartwatch does not look too bulky. By the way, the display is another thing to praise Haylou for. This is a fairly bright AMOLED with a resolution of 448x368 pixels, the text and images on which are easily visible both indoors and in the sun. Perhaps, only the side button slightly spoils the impression of the appearance, which sticks out too much and strives to catch on clothes.

Everything you need (almost)

The main features are the same as most modern wearable devices: support for 12 sports modes, the ability to measure heart rate and blood oxygen levels, control activity, monitor the duration and quality of sleep, and display incoming calls, messages and notifications when connected to a smartphone. There is no microphone and speaker here, so the maximum that you can do is to reject the call and view the message. Unfortunately, NFC is of no use to us, since contactless payments only work in China. Also, the English language of the interface can become a problem for some users, although the icons are quite simple and understandable.

And while the Apple Watch needs to be recharged every few days, its Chinese counterpart provides up to 10 days of battery life with normal use. If you are a more active user, one charge will last about a week, and in power-saving mode, the watch will last about 25 days.
