I am quite happy with my purchase of AKASO V50X. The touch screen works very well and it even supports swipe gestures. Two batteries plus charger to charge them at the same time is quite handy. I always have a fully charged battery.The video quality and the image stabilization are quite good.You can charge the AKASO V50X while recording by connecting a power bank via a micro-usb cable.The camera has input for an external microphone --- not many cameras in this price range do. Akaso sells the microphone for $10. One drawback, though, is that it uses the same micro-usb port and so you cannot charge while using the external microphone.I have not tested the water-proof capabilities yet. I have barely scratched the capabilities of this camera.One of the reasons I purchased this camera was because it comes with a bluetooth remote control that you wear like a watch. I can start and stop video recording by pressing a button.One complaint: The documentation says that pressing the gray video button starts the recording. But it didn't work on 2 occasions and I missed recording 2 important action sequences. But I found out that a long press (2 or 3 seconds) works reliably.Suggested improvement: There are 2 buttons, one for recording video and one for taking a picture. However, the camera has to be in the correct mode. If it is in the video recording mode and you press the red button to take a still picture, it won't take a picture. Similarly, if you are in the still picture mode and you press the grey button, it won't record video. I hope Akaso fixes this with a firmware update.
