Type C charging missing that means charging time is more.
In the days of Type C this one comes with outdated micro USB due to which its not even charge faster and battery back is not that great. I would love the cam that has type C and all necessary features like lens cover type C of course necessary with good audio possibly with noise cancellation option for smoother audio on the go.

Barata y confiable. Cumple con su propósito.
Esta es una cámara de acción muy barata respecto a sus competidores de más prestigio, las Osmo y Gopro, evidentemente, no va a competir con ellas en muchos aspectos de calidad. Sin embargo, si cumple para lo principal, que es grabar secuencias de video, en mi caso, mis viajes en motocicleta. La cámara trae todos los accesorios necesarios para realizar esa tarea, soportes, bases, fundas batería, hasta tarjeta SD.Lo que yo si le reclamo es que siempre se esté desconfigurando la fecha y la hora, es mi mayor lío con la cámara, de lo demás, cumple y por su precio es una genial opción.

SJCAM Upgraded SJ4000 Action Camera 4K30FPS Ultra HD Dual Screen. Excellent to record your tennis!!
I purchased this camera based on the dual screen to record my tennis ground strokes to correct and improve them. So this review is based mainly for this purpose. I don't use the Photo, Playback and Wireless features. I view the recorded video clips on my PC.Pros: - The package come with a battery charger and 2 lithium ions battery with rating of 900 mAh/each and a 32 Gig mini SD card. I am pleased with the battery charger and the free SD card. However I find it more convenient charging the battery through the camera using the mini SD port on the camera.- The front video screen is very useful to properly position the camera when you stick the camera on the back fence (using a small portable tripod hook up with the housing).- I have tried different video settings and the best for me is 720 /30fps. The video clip will not be smaller and the battery last longer with this setting. I just let the camera record continuously for 90mn+ ( I use my own battery with rating of 1350mAh). The video record is split into many 18-minute clips .- There is a small blinking red LED light to let you know that the video is recording.- I review my video recording using VLC app and slow motion is quite clear with 720p/30fps setting.- The video when using the front screen is reversed ( Right side becomes left). I am right- handed but on the video I become a left hand player! There is a setting in the VLC player that let you flip it. Here are the steps: Tools->Effect Filters->Video Effects-> Check Transform-> Choose Flip Horizontally-> CloseCons:- There are little instructions on the user manual. You need to play around with the camera for a while to figure out which button does what! I have owned another action camera before so it is easier to navigate the setting. It would be harder if this is your first action camera!- SD card is difficult to remove once inserted but not impossible, probably due to a weak spring mechanism. I just leave it in the camera when viewing the video. The camera will act as an external USBdrive.In Summary: I think this is an excellent camera with dual screen which will give you options where to put the camera ( the front screen is especially useful when you cannot access the rear screen due to the camera placement). The video quality is quite good with 720p/30fps. I would think it is even better with higher setting based on your need.Hope the camera will lasts.Highly recommended!!!I will update this review if something else happens!
