Haylou is a very impressive offers very hours low prices. From RT LS05S long, 15-20 days operating timepromises. Many (12 different in total) sports and a huge one, 1,28″ display was given space in the clock. In addition, the IP68 according to standard dust and water resistant. But can it do what it promises?

Unboxing - What's in the box?
Looking around the box, you can find the specifications and main features of the watch in both Chinese and English. As soon as you open it, you'll find all the accessories you need. The watch itself is revealed hours, and under the sponge we find the charging cableand the instructions for uset. Only no cartridge, however, this tool no need such as spend oftenthat our telephone charger could not also perform this task. The Haylou RT LS05S comes in the box with the 22mm strap is attached. This is quick and easy to replace, however, the magnetic connectorcan be charged thanks to the no disconnection requireda.
Pairing, activation process
Fortunately even in Hungarian we can also pair our device with the Hello Haylou app, but it is still preferable to use the factory app for several reasons, which I will discuss below. In any case, if you use the original app, all you have to do is download the "Haylou Fun" app from the store, then once logged in, click on the "Connect smart device" you have to click on the sign. Then there is nothing else to do, the system automatican carry out the pairingt.
External
Perhaps the Haylou RT LS05S outside is why the most people will buyi this smartwatch, because it is a looks like an ordinary watch! Circular front panel, quality use of materials and assembly is characterised by.
On the clock side two buttons located in. Top an on/off switch, screen wake up, or Retrieved frombutton. The link Bottom and pressing the calls for sports directly. At the bottom you will find the 
magnetic charger connectorand the heart rate sensort is. A silicone strap gives a sense of quality, convenient. Several holes on it, so it is almost can be attached to any size wrist.
The clock is a huge (1,28″), 240×240 pixels, not too sharp, the TFT paneltechnology's drawbacks (ugly blacks, faded colours) displaywas given. At all I wouldn't say bad, since sufficient brightness, not disturbingly poor quality, however Moving from MI Band 4 (which boasts a pin-sharp AMOLED display) large relapse from this point of view. Nevertheless, for many people the display size, and the surprisingly large viewing angle can make up for the resolution gap (including mine).
Internal
Hardware aspects of the Haylou RT LS05S rather resembles a activity meterrather than a smart watch. Total 2 sensorswe get: a heart rate monitor sensor and a accelerometert. The former is relatively accurate measurementsto implement; in order of magnitude 3 values wrong. Despite this non-medical instrument, the results should be treated with caution! Unfortunately, the GPS, NFC omitted, which may be a decisive argument for many. Bluetooth 5.0-communicates with our phone, which has at least Android 6.0-or iOS 11.0-must run. In addition, a 300mAh battery which officially (with 24h heart rate monitoring) is 15 days, while in practice it is more like lasts 10-11 days at low brightness (but this can be affected by how often you exercise). Fortunately, charging doesn't take long either, about. 2 hours available for upload under from 0 to 100%.
Playing sport
Total 12 different sportscan distinguish: outdoor running, indoor running, brisk walking, cycling, climbing, spinning, free training, gym, basketball, football, and the rowing. Unfortunately, the swimming missed from the repertoire, although this is allowed by the IP68 standard, see the rowing function. A for accurate results we have to take the phoneunkat, as the clock no GPS found, so it cannot produce accurate results on its own. But what exactly does that mean? I tested it, 1 km run After by phone (i.e. using GPS) to accurately 1 km-while I got without 0,9 km, 100 metres off. This is the in its own category outstanding result, as its competitors (e.g. Amazfit Band 5) can even get 40% wrong.
Unfortunately little information during sportwe can read from the clock, in total only 3 datawe see: the elapsed timet, a pulseand the distance travelledot, or from calories burnedt. The latter depends on whether the length of the journey is important during the sport activity. If so, pressing the bottom button will bring up 3 extra pieces of information: the 
average speed, steps taken, and in this case you can see the calories burnedt. As soon as we are launching some sport mode, all other functions become inaccessible, e.g. even the we can't stop the music. In short, it behaves like, as an activity meter, unfortunately cannot offer more in this area.
System
The clock system is quite double for me. All the same works smoothly, however none flooded Haylou RT LS05S lots of featuresval. It has no more potential than the MI Volume 6-and in many ways falls short of it.
Menus
Fanning upwards we find the Main menu itemsat. Here is the performance for the dayus, the heart rate measurementt, a sports activitiesat, the weathert, last the quality of our sleep and view the notifications. In addition, you can currently played music we know stop, skip/skip back. Unfortunately these features do not work perfectly. At the notification (indicated by vibration and a flashing display), if long name or the Text, not available in full. Fortunately, the can display accented letters (in smaller characters), but the emoji plural already not. A music set toat does not appear and the Address, in addition to the regardless of the state of the music always the stop button your bet. To update it, you must use the button at least once.
Under these we find the "More" menu itemwhich is the stopwatchand the countdownincludes. From here we can ring our phone, in case you have lost it (but this only works if the phone is not muted). "Breath training" function, which is can come in handy on more stressful days (this can also be accessed from the main screen by swiping right). The idea is to give you instructions for 1 or 2 minutes on when to turn on and off, reducing your stress levels.
Legalul you will find the settings, where the switch between time sheets (this can be accessed from the main screen by long pressing), from which 5 varieties can be memorised the clock, and 4 levels you can set the brightnesset. This is where the "About" menu item and the switch off and restart .
Swipe down from the main screen to bring up a control console consistencyet. Here we see the Timet, a daythe battery chargeand that our watch whether it is connected a to our phone. You can also access the "Find my phone" (phone search) function, the dimming, do not interfere with the switching on/off of your equipment, and from here you can go directly to the settings.
Swiping right/left from the main screen, you can quickly access the performance for the day, the heart rate monitor, the sleep, the weather, as well as the breathing exercise menu items. A order of menu items in any way not changeable.
Shortcomings
In the clock no night mode, and unfortunately the by raising an arm to no display reset timer, so in the evening, if we're spinning easy be can Contactni a screen. In addition, this function is very sensitive, so it reacts to very small movements, which night in particular confusing can be. A does not limit the brightness even in the evening, so if it would be inconvenient for us to do this anyway we have to do it manually.
Unfortunately, the Water easily can stop the clock, because none to separate mode. Therefore in the shower a without our knowledge we can search a our phonewhich can be a nuisance if everyone else at home is asleep -
Haylou Fun - Factory application
In short: not good, but not tragic.
Thez Haylou Fun application really positive first impressionas the application is in the process of being icons are beautiful, the menu items are clear and the operation smoothness Its structure is very similar to the MI Fit app, the most noticeable differences are in design. A home page we can keep track of the of the day activityunkat, a measured heart rate dataat on the graph displayed, last the quality of our sleept, most recently mass data input (and, if your device can measure blood oxygen levels, its measured data).
From the app can be personalised from timesheet, you can set the automatic heart rate measurement or manually and from here you can access the notification settings is. A do not interfere with operation switching on, timing and wake up can be set here. The Haylou RT LS05S can displayni a calls to, but this we can only reject from the clock. Inaction warning can be found in the functions, and you can also set the display wake-up by raising an armt is. A screen awake time and from time format (24h/12h) can also be customized in the app. Go to weather forecast synchronisation also happens from here.
Overall, the user experience it was good until I started a sports activity. Unfortunately does not continuously update distance data during training, so if a look at from for hours we do not see the current mileage. This is quite annoying can be, because lifted for up to 10-20 seconds at Keep a our armto see the actual distance travelled. Apart from that, I have not encountered any other problems or annoying features.
Hello Haylou - The Hungarian app
The Hello Haylou application Hungarian languagealso has the users who do not understand English may be useful for. But at the same time more compromisewe also need to make.
The application looks a bit outdated, but I'm sure there will be plenty of people who will prefer it. Unfortunately, in order to take advantage of the app all functionswe need to buy the premium version. Unfortunately, the free part quite limited, but even so for use. All in all, I can only recommend the Hungarian app to non-English speaking users without any guilt, but for them worth the premium version of the 750 Ft.
Summary
The Haylou RT LS05S is very mixed feelingsit made me feel. A poor quality displayYou can get used to it, but it's still not pleasant to look at for a long time. From application overall well done, however, the the potential of the clockto not used completely (e.g. lack of night mode). Rationally speaking, it's not worth the price compared to its competitors, yet the watch is really stylish looke can compensate for these (tolerable) flaws for most people. However, if for you not relevant from appearance of the device, I would look at the activity meter market. From MI Volume 6 or even Amazfit Band 5 nice, with AMOLED display boasts a host of useful features (such as measuring blood oxygen levels).
If you like the product, here you can buy.
