Model overview based on user reviews
The Haylou RS4 Plus smart watch offers a stylish design with a bright 1.78-inch AMOLED display and a variety of features, including heart rate monitoring, blood oxygen level measurement, and sleep tracking. It boasts IP68 protection, making it resistant to dust and water, although not suitable for swimming. Users appreciate the long battery life of up to 10 days and the convenience of magnetic charging. However, some have noted issues with the software, such as frequent disconnection from smartphones and limited language options for watch faces. The watch's functionality is complemented by over 100 sports modes, but it lacks GPS, requiring a smartphone for accurate distance tracking. Despite some drawbacks, such as the battery's longevity over time and the magnetic strap's reliability, the Haylou RS4 Plus is considered a good value for everyday use and workouts, especially for those who prioritize a great screen and reasonable price.
Pros
Cons
1. Design. The watch looks stylish, although the shiny frame seems a bit feminine, I would prefer a matte one, but I got used to it over time. 2. Magnetic charging. Despite reviews, the charger holds firmly, even with a gentle sway it does not detach, unlike the Redmi Watch. 3. Autonomy. The charge of 78% that the watch arrived with lasted almost 9 days—an excellent result. I connected it to an unofficial app, which has more settings than the recommended one. 4. Screen brightness. At medium brightness, the screen is easily visible both day and night, maybe because it's autumn. It's a pity that you can't set automatic brightness reduction at sunset like in the Mi Band—it would be useful in summer. 5. Straps. The universal mount allows you to change the strap to any from the watch's brand, which is very convenient. I tried a silicone strap while riding a motorcycle—it holds securely and doesn't unclip. 6. IP68 Protection. The watch withstood water—you can wash hands and dishes, which I did. The main thing is not to press the button when the watch is wet, as moisture can get inside and break it, as stated in forums. 7. Heart rate measurement matches my tonometer. 1. Dials. Only options in English or Chinese are available, which is a bit disappointing. The ability to install Russian and Ukrainian dials, as in Mi Band, would be useful. 2. Notification icons. Some apps, such as Telegram and banking apps, do not display correctly, and it can sometimes be difficult to understand where the notification is coming from. You cannot add icons. 3. Support for emojis and custom firmware. The watch does not display emojis and other symbols, only standard fonts, and you cannot install third-party firmware, which is available in Mi Band with the help of an app from kind Indians.

Overall the watch is good Bright dial, waterproof. 1 - While the player is operating, the time is simply not displayed at the top; they could have at least made it in small print. 2 - The battery exhausted its resource after 2 years; now it doesn't even charge, although it shows 100 percent charged, but after 1 hour, the charge drops by 10 percent.  Miroslavchik: use Haylou RS4 Plus more than year |
the strap included is magnetic - it's better to replace it right away - it falls off and doesn't hold well on the wrist. The watch overall is excellent, with lots of training programs, heart rate measurement, everything is great except for the unfinished software - which constantly loses connection with the smartphone and is difficult to reconnect. great screen with acceptable bezel thickness, sufficient brightness, everything is clearly visible on a sunny day, functionality, the battery lasts very long if the connection to the phone is turned off! You can set the alarm directly on the watch, the vibration is decent, excellent appearance, reasonable price. raw software, often loses connection with the smartphone Maksim Konopeltsev: use Haylou RS4 Plus few months |

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.

Likely, in a few months, I will use them as regular watches and a workout tracker, disconnecting from the smartphone, as often happens. My rating: 7/10. The watch is good for everyday use and workouts but may seem too simple for demanding users.
