The product seems to be as advertised, I adjusted the settings and now we'll see how it performs. I still need to test if it's waterproof or not but for now I'm satisfied. The only off note was the delivery, as the courier delayed it for a week. Thank you.
Excellent and fast delivery, the working principle of the watch is as described by the seller. The watch material looks very textured, the strap is soft, and there is a powerful flashlight, which is a great purchase 👍
It looks very good, solid and presents nicely on the hand for this price. I recommend it. Could you add etched glass?
The waterproof performance is better than i imagined, and i often wear it to wash my hands. Intact and undamaged, it proves that the product is waterproof. 👍 👍
High quality watch, elegant appearance, exquisite craftsmanship, and excellent screen display effect. Even in strong sunlight, the screen is clear and visible, and it is easy to synchronize with applications. You can change the clock dial type you want to use. The measurement of ppm and blood oxygen is very accurate. The strap is very soft and comfortable to wear. As for the goods, they are delivered quickly and can arrive in less than 2 weeks. The packaging is also very good. 🤩 🤩 🤩 , top seller 🎉
Good watch！
The product packaging is perfect, the delivery is fast, everything runs well, the clock is very beautiful, and the functions are diverse
Cool!
Super
This is a very beautiful watch. Exquisite appearance. This is really cool! This smartwatch exceeded my expectations in terms of design, functionality, and battery life (1000mah). The seller introduced me to many excellent features, including high-strength waterproofing and support for swimming while wearing. Accurate motion tracking and heart rate measurement, high-precision blood oxygen, over 100 exercise modes, making and answering phone calls, message notifications, voice assistants, ultra high definition screens, are definitely recommended good products!
Product is ok...thanks ffrom belgium . 👍 👌🏻
Very simple watch. But for now, it works perfectly. I hope it lasts and doesn't give any problems. The last one lasted at least a month. It turned off and didn't turn back on.
Great work, i am delighted. 5 stars
Super watch, i like it 😁
arrived well before the date
absolutely impeccable, no strong smell, waterproof and cold-resistant (placed in the fridge for two days) Very aesthetic construction and great electronics. Highly recommended
Excellent watch tells perfect time up-to-date on the weather update a flash. Light is bright and very useful. Thank you.
The watch is quite nice. If you have large hands, this is your watch because it is very big. The only downside is that it doesn't come with a screwdriver to adjust the metal strap.
