Creator of the buyforlife.com site here :). Source: over 2 years ago

Very cool, that is actually how buyforlife.com started too - as a simple list :). Source: over 2 years ago

Same experience here. To solve that, I built a crowdsourced website that collects all sorts of high-quality and durable products: https://buyforlife.com. Source: over 2 years ago

That's why I built buyforlife.com to tackle these issues. The goal was to build a sort of "Productpedia", where people can search and filter through the most durable products of the world, constantly updated and maintained by the community. I stopped working on it because I was busy with other work and it never really gained sustainable traction. Source: almost 3 years ago

Buyforlife.com and recorank.com use early versions of reviewr.ai. More will emerge in the near future. Source: about 3 years ago
