I didnt like this product. Because I bought this camera around 4months back. And once used this for video. By that time it worked. Later I didn't use this nearly two months. Then I bought sandisk 64gb CLS 10 SD card. When I inserted that card into this action camera once its worked, I mean I recorded one video. Then I removed SD card. Done, everything was correct, but when I reinserted SD card next day then problem started. When I switched it on without SD card it shows 'No detectable TF card, please insert TF card'and then its off. I shocked, what's happening with this! ? Then I inserted SD card. Then I switched it on. For long time like 50 seconds to 1 minute it has taken time to on. Then again off. Many times I tried with other SD card also. But its no use now. Then I asked in sjcam website, Facebook page but no reply from them till now. They ignore the customers. They won't reply. If they won't care about customers how can they grow the company! ? So I won't suggest people to buy their products.
