User reviews
User Reviews & Feedback Analysis ⭐ 4.7 (43 ratings)
Authentic Feedback Analysis:
⭐ 5/5 | J***r: Top-Smart-Watch based on ESP32 for developing own firmware or software. With many sensors and an 868MHz transceiver, WiFi, Bluetooth, IR, microphone, speaker, vibration motor, ……………..
⭐ 5/5 | D***i: Excellent, I loved it, I installed new firmware on it!
⭐ 5/5 | К***ч: Packed perfectly in plastic. Everything works.
⭐ 5/5 | Ч***й: The quality of the product meets expectations.
⭐ 4/5 | М***ч: I didn’t check it myself, my 12-year-old son has already reflashed the watch, so it’s okay!) It looks nice to me, but it’s impossible to rotate properly; it barely sticks out.
⭐ 5/5 | AliExpress Shopper: Works as expected. I can write firmware in c, c++ and python. Now i can learn esp32 with many additions including the lora
⭐ 3/5 | М***ч: The design of the regulator button is recessed, which makes it very inconvenient to use.
⭐ 4/5 | AliExpress Shopper: Sleek, lightweight, and the screen color pops. Easy to tinker with — open-source code ready to hack in PlatformIO or Arduino IDE, no fuss. Battery’s decent if you pick good firmware, but LoRA chugs juice like crazy —turn it off unless you need it. Touchscreen taps/swipes can be a bit unresponsive, but for the price? Worth it.
⭐ 5/5 | AliExpress Shopper: The watch works. I went to meshtastic flasher website and selected the watch model and flashed the alpha (newest) version of meshtastic, it took 20 seconds only. I successfully communicated with other users using the mesh network with the watch.
⭐ 5/5 | AliExpress Shopper: Arrived as expected, original and in working condition.
⭐ 4/5 | R***z: Package received just in time. The watch is working properly, and I have managed to upload firmware from Visual Studio Code using PlatformIO to the device. I would have preferred it to come with USB-C, but it comes with the cable so I have no complaints. I’m looking forward to seeing everything I can do with this device, eagerly anticipating the TWatch Ultra. Greetings!
⭐ 5/5 | F***l: Compatible with Bruce firmware. She arrived earlier than expected.
⭐ 5/5 | M***A: Very good
⭐ 2/5 | l***i: I waited a long time for this item to arrive, tried it, and was not satisfied. There is difficulty in touch, you have to press multiple times to navigate the menu and select. Disappointed with this item. I have other Lilygo devices and they work well.
⭐ 1/5 | t***c: article does not work, battery is poorly soldered.
⭐ 2/5 | AliExpress Shopper: The battery lasts 4 hours max.
