I had one similar but this one was improved.You can see how it's being recorded in a new second front screen. Better quality in general, and you get a better video because you can see wider landscape. I'm glad I bought this one.

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.

It's nice for the price. lil more than an hour of battery and you get 2 of them, again very nice for the price. Resolution is 720p, sure it scales up and increases the file size doing so, but the image quality doesn't improve. Makes a great dashcam and decent webcam, accessories are a must unless you only need dashboard or helmet mounts and trust sticky tape..

*update*The company reached out and kindly Sent out another camera. The second camera seems to be improved. My one suggestion is if you buy this camera to get your own SD card because the one provided doesn’t work.So i bought this camera on my wife’s amazon account since she has prime and i don’t, anyways for reasons like everyone else, to spend $50 on an action cam vs the go pros that are $300 - $500+When you receive this camera it comes in a really nice box, and actually feels like good quality and the attachments are decent. But once you turn it on and go through the features you start to realize why its $50. The micro SD card got so hot on my first use that it burned my finger trying to take it out, literally BURNING HOT. So i went to Walmart and bought a 64 GB SD card and it was fine, then i rode my motorcycle to work and it kept turning completely off. And had random 3 minute videos here and there. And to top it all off it doesn’t have blue tooth, it connects via “wifi” which it the dumbest way to connect a camera to a phone because the signal gets lost constantly unless you are near a hotspot ect. So in my opinion save up for that GO PRO camera you keep looking at and skip this junk, i am sending it back asap

Plenty of vids on tube. Similar cameras same characteristics out there. User interface takes getting used to . Getting some more mounting options . Unknown if I will ever use front screen . Seems within focus 20 inches away from subject , wide field of view. Purchased some other mounting options . Seems to be standard (ie:go-pro) . Waterproof ..., case great . It does cover mic port, and additional plastic for image pick-up . SJcam app works , limited wi-fi capability . Didnt like older Sammy sung Note 3 . android OS .... Satisfied - while still testing capabilities . Fast shipping ! ( Not using phrase associated with Hoover )

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!
