Cheap and best but a small flaw in the product it self
Its the best budget action cam but it has a production flaw as it can't be used with a 64gb memory card as smooth as it can be used with a 32gb memory card it goes blank showing only sjcam logo then all u need to do is eject the memory card and turn off it then turn on the place the memory card then it works just fine but needs to format so u better back it up all the time u chane or remove battery for charging

Not worth
Battery life is not stable, some times it last for 1 hour 15 min, some time for 30 to 40 min, randomly get restarted for no reason, and no option to connect external mic, I have a mic & tried I connected with micro USB to 3.1 mm jack converter, it don't record the sound, & I realized the 2 Micro USP port on the camera is only to data transfer, voice record is not possible, voce recording can happen only with the inbuild micro phone & while using water proof case - voice is not recordable as it is tight vacuum packed in the case & no options available in market which can record a voice in water proof case, I give a big NO for this product cos of no voice recording option.

You don’t get what is mentioned in the box
I ordered this cam and on delivery I noticed that the mounting frame is missing, hence I ordered replacement and the replacement received also does not contain mounting frame which is basic to attach camera with the helmet or motorcycle mount etc.!!!

Not original sjcam!!
THIS IS NOT AN SJCAM. I enquired with actual sjcam and they denied this product. I had bought it already and the app they ask you to download isn't from sjcam. Quality wise....ok-ok-video.... and audio is terrible (for the price it's great). Basic accessories present. Good packing and quality materials used(edit: they broke apart within 2 weeks) for the accessories. No stabilization since the price is very low(come on 4k@30fps and 2.7K@30fps with Wi-Fi and couple of accessories at Rs.4.9K?).Final verdict, for the money it's good. Best for starters who aren't sure if they should get a action cam or not. Else go for sj5000x elite or sj4000 wifi. Thank you.Edit 2 I stopper using it in 2 months because the video is waste. I rather tie a galaxy Y to my helmet and record. Trying to sell for 1000 now
