### 1/5 — **CONFIRMED SPYING**

*2023-01-19, version 1.4.9*

DO NOT download this app or buy this Chinese SPY GEAR. Pretty unforgettable experience, after reading other reviews about it being an opportunity for spying, my girlfriend and I laughed about it. She jokingly typed into Google translate things like “I know you’re listening Chinese spy”, she translated it to Chinese and played the audio right next to the charger. Seconds later a male Chinese voice started speaking through my cars speakers!!! My phone was not plugged in and it was heard by both of us!!! We checked if there was any other factor that might have played audio and there was no way. I know it sounds nuts and I don’t know how it’s possible, but I’m pretty creeped out nonetheless. First review I’ve ever made on an app. Nothing else to say besides I’m returning the thing tomorrow morning.

### 1/5 — DO NOT BUY!

*2023-01-10, version 1.4.9*

I bought this for the Bluetooth specifically and it doesn’t work! It makes you play music through the app and it cost money for the app it coworks with. It’s absolutely trash!
