Lots of products have <4 stars on Best Buy's website. If you're not seeing products with < 4 stars, you're just looking at their featured items.

I also agree its hard to trust online reviews, but we don't need to throw out falsehoods about how every product is 4+ stars.

To be honest though, if you were a retailer trying to push the idea that almost any product you sell if cool tech, wouldn't you probably remove most SKUs that are genuinely 2-star products?
