yea those sj4000 were no good the video skipped and stopped at some points and the video was not 1080p so i ordered another one this one supposed to be a sjcam but we will see what shows up if nothing else i have a lot of spare parts and i saw something about fake memory  cards and the way they record could have something to do with it but you cant tell them from one or the other they said like the 128 gig only have 8 gig of writable space so it looses video quality
anyway we will see what happens
