Review on AURSINC ESP8266 WiFi Deauther Watch V3 Development Board with OLED & Laser, Wearable Smartwatch - Attack/Control/Test Tool for DSTIKE NodeMCU by Patrick Clifton

At first I was a bit disappointed when I saw that the internal battery is smaller than advertised. That listing says 600mAh and there's a Chinese cell that says 500mAh when you open it and considering this is a low power device that makes a big difference. After some simple tests, it later turned out that although the cell has Chinese letters, the run time appears to be a real cell, and the displayed current also appears to be accurate. As with me, there is enough space inside for a large external antenna. I used my soldering iron to melt a notch in the plastic spacer so everything closes properly and the end of the antenna sticks out and now I have slightly better range than my laptop and phones (Lenovo T530, iPhone 7+, iPhone X). I also did another quick test where I set up a router in my shed and connected to it across the yard and I managed to connect it to the watch as well and it worked. Considering there are newer versions of this watch with some minor issues like the watch resetting on power off (ironic, a watch that doesn't show time) and a slightly smaller battery, I would personally give it a 3.5/5 that's a bit expensive
