I bought and tested this watch! It contains a trojan (trojan virus =) installed in the video program. My antivirus detected it immediately and I snuffed the beast ... 3 hours cleaning my computer later, it will! If you have patience, then good luck. For my part, I completely disassembled the machine so that it can no longer be used and left in the trash directly. SAV? for what? Refourguer this watch to another? Bin no, I'd rather lose a little money, not bad! Solidarity with the community!
