I have had it for about a year, purchased from Amazon.uk on sale for about €120, and it replaced a Huawei Watch GT (Gen 1).

The reason I bought it is for the Wear OS, to have more capabilities compared to a typical smartwatch. It supports esim (so it can be used as a 4G mobile) but with patents, there are relevant instructions on the internet. I haven't tried it myself.

Pros:
- Sturdy construction and large size, ideal for a male wrist
- Very good battery life (for a Wear OS smartwatch), easily lasts 2 days - even 3 if WiFi/GPS (fitness tracking, etc.) is not used much, thanks to the use of dual screens
- Supports Google Wallet, so you can make payments everywhere with the watch
- Accurate measurements, I don't have a point of comparison but I don't see significant differences compared to my friends' watches when we run together
- Overall, it is fast and responsive thanks to the very good hardware (CPU, RAM, ROM)
- Recently upgraded (with great difficulty) to Wear OS 3.5, which will likely be the last update it receives
- Clear sound for calls (microphone and speaker) through the mobile phone
- Notifications work well, you can read email previews, messages, Messenger, everything, and you can reply (although it's difficult with such a small screen keyboard). It also supports Greek text properly.
- Good mobile app, provides various information without being something special
- Infinite watchfaces, both through the Mobvoi app (TimeShow) and third-party options

Cons:
- Not waterproof: It's okay for rain, possibly even for swimming pools, but if you read about the water-related issues, you won't risk it.
- After the upgrade to 3.5, it doesn't have Google Assistant. It's not the company's fault but Google's (Wear OS). It was incredibly useful while it was working.
- There is no repair center, so if it breaks within the warranty period, you have to contact the manufacturer directly (China) to sort it out. If it's out of warranty, you just cry about it.

Overall, it is a decent smartwatch, with many capabilities and good hardware, but with support issues (see the upgrade to Wear OS 3.5) and construction problems (e.g. read about battery swelling, waterproofing issues, etc. that may also appear in other smartwatches).

The best thing right now is that it works perfectly, especially with Android. With iOS, it loses some of its functionality. Highly underrated, easily on par with the Galaxy Watch 4. The battery is amazing. The LTE model has 2-3 differences compared to the Pro 3 that are not very noticeable at first. It locks onto GPS (GLONASS) more easily, NFC for payments works flawlessly, and it will also receive the new Wear OS due to compatibility - Snapdragon Wear 4100 instead of 3100 or 2100. 1GB RAM and 8GB ROM
