A 4.7 looks straightforward. It can be produced by two completely different sets of buyers, and one of them should worry you.
Look at how many ratings
Five ratings averaging 5.0 is four happy friends and a stranger. Ninety ratings averaging 4.5 is a real signal. Below about ten, the average is noise.
Look at the spread
Mostly fives with a couple of fours is an item that works for nearly everyone. A pile of fives and a pile of ones, averaging the same, means it works brilliantly for some setups and not at all for others. Find out which group you are in before buying.
Read the low ones first
They are where the specifics live. Five-star reviews say "great item, thanks". One-star reviews say "does not work on PHP 8.2", which is the fact you actually needed.
Check when they were left
Thirty ratings from two years ago describe an item that no longer exists. Recent ratings, even fewer of them, describe what you would be buying.
Every rating here came from a purchase
Reviews can only be left by somebody who owns a licence, so nobody is rating an item they never used. That makes a low count meaningful rather than suspicious: it means few people have bought it yet, not that reviews were removed.
