Be mindful of confirmation bias when searching reviews. Finding 10 reviews mentioning noise might be because it's noisy, or it might be that they have thousands of reviews and a small percentage experienced noise
This is an excellent point!
I suppose I could normalize by the number of total reviews.
It hasn’t been an issue so far as I am only filtering out cases when there are multiple reports of the same issue, and I care more about eliminating bad options than detecting all good options.
