4chan general threads. /g/ for tech, /diy/ or /out/ for tools and gear, /ck/ for cooking and more.

If you need to actively find a review for some item you want to buy it's probably not that great of an item imho.

[Fyrezerk]

I'm not entirely sure what that implies. It's in the consumer's best interest to check reviews of products when selecting something to buy. How else would you wade through competing options?

Furthermore, 4chan has no search feature so I don't know how that's even equivalent.

There's a search function in the catalog that can fulltext search all threads.

/g/ has "an audiophile general" for example that comes with recommended places to buy, tierlists and reviews.
