    Beware - Few Instructions Fiddly Software!
    Color: dark
    Against my better judgement I'm going to go ahead and keep this little device since I was able to figure out how to move around in the software. So these are first impressions, but clearly, I'm not impressed so far. If you're not comfortable with pressing buttons to see what happens then I'd advise you to look elsewhere. The device is packaged nicely, and when plugged into power, it popped right on and started recording. I know the product description says it comes with a 64 gb TF (mico-SD) card but the device's specs say it's only capable of seeing 32 gb. To get the card in and out of the device (because the only way to save videos is to remove it from the camera, put it into a card reader and plug that into your PC, laptop, or smartphone) both the power cable and the rear facing camera cables have to be unplugged. The instructions say it comes with a suction cup mount...it does not. You have to fiddle with a sticky pad to attach to your windshield, pull the cover off the other side and attach the camera to the sticky pad. Make sure the camera is placed where you want it because you only get one shot apparently. We'll see how it does, the picture appears clear on its little screen and it plays videos back quickly, it's just extremely fiddly moving around with the buttons and there are NO instructions how to get to those functions. But, it is what it is, and you get what you pay for...the jury's still out on it's functionality.

    Works great!
    Color: Green
    Works great and doesn't pull hairs. The guards are helpful. The battery has last me a very long time. If you have a baby or child this would be a great option to cut their hair because it isn't super loud like regular razors
