 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation. More »
Why does UserBenchmark need so many captchas?
Our servers must handle malicious traffic because our user-focused service leads to less profit for brands. More »
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products. More »
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands. More »
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 15 years publishing real-world data for users.
