I know people in China who wrote false reviews for free stuff, so what do you suggest to find quality when ratings and years can't be trusted?
First thing is to keep all the interesting survival stuff in your cart or wish lists, the fake companies don't last that long so they will vanish after a month or two leaving the better choices.
When it comes to fake reviews, they tend to be short, and simple, often having an obvious double translation grammar error in there, so look at the ones with the longer reviews that people would have spent time on and know the values to which the product boast and speak to those. They have started throwing these in in alternatives to english so that you are more likely to ignore grammar errors so beware of that one too. They will often speak of qualities that don't really matter.
At the minute I am keeping an eye on titanium wood stoves, knowing the features of titanium comparisons here helps. A real titanium stove at a decent size will weigh in at between 1-1.5 kilo. Many of the ones on ali now are quoting 2.4-2.8 kilo, clearly using non ferrous steels, which is fine if you just want a cheaper steel stove, but point is, knowing the features of the genuine versions can help...
The other one is ytube, people are learning to use ali and have started talking about some of the side companies, like toaks for ti kitchen ware. They are almost identical to some more popular brands but at a cheaper good price without compromising quality.
Another one is a brand of down sleeping bags, I can't recall the name right now, but it has become popular within the community.
Theres no guarantees of course
Oh, another trick, if you can't find something but can find similar things, dump all of them in your cart, come back in a week and free scroll through the suggestions, you will often get what you were looking for the first time.
Hope that helps, it's all I can think off right now.
