I still buy a lot of stuff from Amazon but I have found that I cannot trust their review system at all. So all research is outside Amazon or else I'm basically treating it the same as Alibaba. The thing that utterly destroys credibility in my eyes is that fraudulent sellers are able to target name brand listings by offering fakes at a slightly cheaper price than the original manufacturer. There are apparently some mitigations against this but their use must not be widespread among sellers or something because I've been burned by this.
