Personally I like the interface and think dumbing it down would be a mistake. I would recommend adding a "minimum reviews" filter, as I sometimes sort by avg rating but get things with 2 or 3 reviews that are probably fake anyway.
You can do in two steps by jeviz.com.
1-) Choose sort by Most Reviews, which is an sort option Amazon generally hides
2-) From Average Customer Review choose 4 stars and & up
this will sort all products that are 4 or above stars but in most reviews order.
Yeah, I always look for something that has been reviewed by at least 5 other people.
I found most of sort features by try and error. I will look into it if Amazon provides it I will implement it.Thanks for the feedback.
Oh, you're not running the search over your own data?
No I am directing to Amazon with right search query url.
