Neat idea, seems kinda useless unfortunately. Since it’s entirely crowdsourced (I assume from my brief visit), you’re getting very anecdotal information, and I think it’ll be biased towards people who’ve had bad experiences with products. Feels like you’d need a huge community of pretty dedicated contributors to make this work, and I’m skeptical that can be built from the ground up for this narrow purpose.

There’s also looria.com/reddit, which gives product recommendations based on the thoughts from different hobby subs. :)
