Review on Vantrue X4S 4K WiFi Dash Cam With 24/7 Parking Mode, Night Vision, GPS Compatibility, Motion & Collision Detection, 1080P@120FPS, Capacitor, And 512GB Max Support by Andy Metzger

This is all in all a quality product -- so far so good at least. From the smooth overnight shipping, to thoughtful packaging and user manuals presentation, and of course the product design and performance itself, I'm honestly impressed A to Z. It also comes with a plastic tool which you can use to pop out the SD card and tuck the wire out of sight in your car, that I think is going an extra mile and didn't go unnoticed. The suction cup, by the way, is as sturdy as a suction cup can be. You turn the tab to tighten as opposed to flipping, making it more durable and reliable.You do need to supply your own micro SD card which you, by the way, should insert before powering it up, lest you get an invalid SD card message when you format it. I use one with 128 GB but you can go up to 256 GB. Another tip is to make sure you remove the magnetic lens protector film, or you get blue tinted video like I did initially. The default resolution is 4K at 30 fps. No complaints about the video quality, it's all right on point. But I prefer 1080 at 60 fps as it's more smooth and practical for me. The screen display is pretty much the entire back area of the dashcam; therefore, it feels large. The 4 navigation buttons are ergonomically positioned, and the most important button, the emergency event save button, is unambiguously and intuitively placed at the top right where a camera shutter button normally is. I like that a lot.I also like the USB C connection to the device, so it's a snap to connect. Also 2 separate cords are provided, one for the car cigarette light and one for the USB A. It's very nice you have the option of connecting the power cord to the suction cup apparatus which in turn powers the dashcam. As a geek or sorts, I appreciate these design details. That being said, the range of movement for adjusting the camera angle is rather limited. But I suppose it's not an issue unless you have a lamborghini. I didn't try the parking mode as my car doesn't have constant power when the engine is off. I did play with the time lapse mode which may have a special use case outside of parking mode and I'll keep that up my sleeve.I did attempt to contact customer service / tech support just to get a feel. So there's an online form you fill out and you'll be contacted within 24 hours. In my case, it was within 10 hours via email. It's OK but I prefer if there's a live chat available.One negative so far is the Wifi for the app. The dashcam can host its own Wifi network so you can connect your smartphone to it to change settings and playback videos. Connectivity is flaky - it's been frustrating that sometimes the SSID shows up, sometimes not. But it's not one of my use cases anyway. I prefer to view and video on a big screen as opposed to on the dashcam or a smartphone. The price point is also on the high side, but that normally comes with quality. Overall, I feel confident to recommend this dashcam to my friends and family.
