  • Good product ,but not to easy to use
Color: Black
Well after doing lots of research of this type of cameras decided to buy this one, first because of the price compared to other similar ones,, the problem is that it's not that easy to use and all the features on the commercial video are not true,, no zoom and no stabilize video images,, the touch screen commands are not too sensitive either and had a problem with with the menu,, video editing is a pain because it needs a program that has to be purchased or download for free with lots of glitches,, so i have not really using this camera a lot , is just ok nothing greater...!!! ... show more

  • Leave the battery out and use a cable to power it
Color: Black
I found that using the battery to run the camera causes it to heat up so much you can burn yourself touching the camera. So I just remove the battery and plug it into the USB slot and run it directly that way. And lastly the microphone sucks. I wish they had an extra port to plug one in to. Other than that it is a great little camera. Me and my friends have bought a few now. ... show more

  • Nice camera at a great price-point
Color: Black
I’m not an action camera geek, so my review is based on an amateur’s limited usage under fairly tame conditions. My main use is for driving, as there are plenty of dangerous situations on a regular basis when driving. Now I have the ability to provide video evidence for the police in the event someone is doing something stupid. You will need to purchase a mount for your vehicle if you intend to use it for that purpose. The picture quality is good for what I use it for and for the price point, although the audio could be better, but again, not bad for the cost of the device. The waterproof case seems to work; however, I don’t see a situation where I will need that feature. I placed it in a sink of water just to test it, but haven’t taken it into deep water, so not sure how it holds up to those conditions. It does not have a remote control, which could be a dealbreaker for some people. There’s an app so that you can remotely control the camera, but I haven’t had the need for that, so I haven’t tested that feature, but others have said that it works well and is a great feature. Pros: • The video quality is very good for the price • So far, the battery life appears to be good • Fairly straight-forward to operate • Pictures and movie capabilities underwater from what light testing was done Cons: • None to date for me, but I’m not a power-user by any means Conclusion: • Based on what I’ve seen, this camera seems like a great value for the price and I think it’s worth your consideration if you’re looking for an action camera, especially if you need one for underwater purposes. ... show more

  • SJCAM Upgraded SJ4000 Action Camera 4K30FPS Ultra HD Dual Screen. Excellent to record your tennis!!
Color: Black
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-> Close Cons: - 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 USB drive. 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! ... show more

  • Horrible quality
Color: Black
Bought 2 of these cameras for my kids to use on vacation. The micro SD card was literally stuck in one of the cameras and it will not come out at all. Finally after prying with tweezers it began to come out, but the card broke and we lost all the videos my son had taken. Very poor quality.
