Very beautiful little watch, and in general I was satisfied with its connectivity and measurements. What annoyed me was the strap, which because it had a magnetic closure, would open with a sudden movement. Several times it had fallen on the road.. until I eventually lost it...
In general, it is a good smartwatch, with a nice Amoled screen, vibrant colors and contrasts, and very smooth animations thanks to the 60hz refresh rate.
It does not have a microphone or speaker, so you cannot make calls through your phone. Its measurements are decent, the application is user-friendly, but one downside is that it does not support Greek in the menu. However, it does support Greek in notifications, so you can read them normally.
Fair watch. I wasn't crazy about the strap so I changed it right away.
It does its job just fine. In terms of charging time, it charges relatively quickly and also lasts, I would say.
Overall, it looks quite nice and its screen also has good resolution.
The watch for its money is very good! I have it for 1.5 years without any issues. Very beautiful, nice construction, great screen, very good battery life, 2 minus stars, 1 for the strap, I changed it as it was easily coming off my hand, and another minus star for the application, they have forgotten the upgrades, the backscreen renewal has not been updated for over a year, I got bored of it, otherwise it is value for money!
I don't know, I read the comments about the water. I want to say that I never take off when I shower, and I have also taken a bath in the sea 4 or 5 times and nothing happened. As for the leash issue, I have the classic one
Attention to those who buy it to change the magnetic strap because you lose it for fun. It broke in a month, stopped counting, the sensors don't work, they don't emit the green light, just like the battery started to drain in two days, maybe due to the above damage. Also, the touch started to malfunction at the end. It never went into water.
Stay away, you will waste your time and your money
Good morning, I didn't expect the situation to be so bad, the watch is not protected at all from humidity, please keep in mind that you don't need to wash your hands, just the sweat from your body will destroy the watch. It hasn't even been a month.
I did not like the magnet on the strap at all, it does not fit well on a thin woman's wrist.
Furthermore, I find it unacceptable that it does not have settings in the Greek language.
I synchronized the time!
Edit: Notifications only come from calls, SMS, and emails, nothing comes from other applications even though I have selected them.
I ordered another strap because it was coming off my wrist while I was sleeping!
Other than that, it is fine in its measurements and its battery lasts as promised!
First of all, it is very elegant. Aluminum construction, silicone strap. It came to me with the classic strap that closes and not with the magnetic one, and in the box, it actually shows the "new" strap. The company probably changed it and did well because the truth is that the magnetic one was bothering me.
Very reliable measurements of both heart rate and oxygen. Red LEDs are used to detect oxygen. The sleep monitoring is also very nice (currently missing REM).
Screen: a delight for the eyes. The menu/user interface is well-designed and high-quality.
Haylou Fun app: it has some bugs, such as issues with syncing the weather with the watch or sometimes displaying the message "the network connection is abnormal." It may test your patience to connect, but once connected, there are no issues. You will find basic information and slightly more detailed details regarding sleep tracking, sports, and watch faces to change on the watch.
It no longer measures skin temperature. The company has temporarily withdrawn this feature because many confused skin temperature with body temperature (which is different). Therefore, to avoid any misunderstandings, they removed it. However, they added some other features such as "one tap measurement" (measures blood oxygen, heart rate, and stress with one click), battery saving mode, to-do list (notes), etc.
For a price of 55-60, I don't think there is anything better. It may not have GPS or always-on display (there is a function that stays on for up to 30 minutes), which, personally, I find unnecessary, but the watch is decent in all other aspects. Straps can also be changed, and there are options available on the market.
Edit: There was an update both in the app and on the watch itself, and it seems that the bugs (weather and stress) have been fixed. 5/5 stars.
Very nice! The screen is incredible and the measurements are accurate! The Haylou fun application is a bit problematic, but we hope it will be fixed in the next updates.
Just received it today, as soon as I opened it and saw its amazing amoled screen, I was amazed by the quality of this watch (coming from an Apple Watch 4). There are plenty of watch faces to choose from, both elegant and sporty. I deducted one star because the menu is in English (although notifications come in Greek), hopefully there will be an update in the future to have a Greek menu. Another thing that might bother some people is that it doesn't have GPS, so if you are into sports, I don't recommend it. However, I always have my phone with me when I go for a run, so it didn't bother me much. At this price, you won't find another watch with such an amazing screen, so anyone considering it should buy it without hesitation, it's worth the 50€.
*update after two days* The watch itself is very good, what really annoyed me is the strap...those magnets drive me crazy because after wearing it for a while, it feels like it starts to loosen up (it doesn't come off the wrist, it just feels a bit loose). Now, I don't know if it's a problem I have because I have a small wrist...but I will definitely change the strap. So, keep in mind that you might need to spend an extra 20€ if it doesn't fit you well.
The watch has a fantastic display, on par with smartwatches that cost 100+ euros. The colors, brightness, and 60Hz give you the feeling that you are using your smartphone, and it is far superior to other cheap bands or watches with AMOLED (former user of mi band 5 and the difference is chaotic). It does not have AOD, but you can set the screen to stay on for up to half an hour continuously. The measurements for exercise, steps, oxygen, and heart rate are very accurate (of course not as accurate as a medical tool or a Garmin watch), maybe only slightly off in temperature measurement. The connection to the phone is very easy, the mobile app is almost a copy of Xiaomi Wear, and I have not experienced any disconnections on my OnePlus phone that I have connected. It recognizes Greek characters in messages normally (it does not recognize emojis), but I did not see an option for Greek in the menu. There are quite a few watch faces (100+) and I consider about half of them to be good, while there are also third-party apps if someone wants more. The strap, for me with a medium-sized wrist, does not feel like it will come off or the magnets will open, for women with smaller wrists it may be even more secure, I can say that its magnets are quite strong. Overall, a value-for-money watch with many functions and sports. Obviously inferior to smartwatches that cost 150-200+ euros, but much better than anything else I found at 50 euros.
Edit after one week of use: With the factory charging, the watch consumed about 15% of the battery every day. After I charged it myself for the first time, the battery consumption was limited to about 8-10% every day with the same settings enabled.
Fantastic AMOLED 60Hz display (much better than other watches over 100+€). The mobile application is very user-friendly, not at all complicated, and does not disconnect from the watch. It's worth it!!!
