A woman I know bought a Rexing without consulting me, even though she knew I was heavy into dashcamming, and all because it had an affordable price and tons of 5-star reviews. She wanted it for parking recording and didn't get a HWK, didn't realize her tiny car battery wasn't going to give her more than a few hours anyway, and she was trying to run it on a 4GB card
I gave her my newest 64GB Samsung card, did the install, and told her the bad news about parking protection, bot offered to do a HWK if she bought one. I don't think she even uses the cam anymore
Lotsa tales like this where people didn't know, didn't look deeper, but just bought based on the stars they saw in their eyes
From what I've heard that company was playing the review game as recently as 18 months ago, dunno if they still are, but I've been waiting to see their name and a lot of others pop up in this thread.
There's hardly any way to fix the problem and keep a review system; whatever measures are taken will be met with counter-measures to get around them in a never-ending game of cat and mouse
Semper Caveat Emptor.
