I will post this review everywhere on the internet, as long as you do not send me a replacement product!
I have bought an A10 camera 6 months ago, but had 2 issues straight off the box :
1) The SD card can not be removed by fingers. It stucked inside
2) The camera isn’t compatible with external microphone, in opposition as the official website specifications
After contacted the SJCam warranty support, they admitted their error for the point #2 but nothing about point #1. They accepted to exchange the defective camera, but later on, stopped to answer any emails. So they do not offer any warranty support. Their quality and attitude are garbage.
BETTER TO SPEND YOUR MONEY ON OTHERS COMPANIES
Also, they daily remove the bad “customer reviews”, so you can be sure their REVIEWS are TOTAL FAKE.
