The issue with those tools is that Amazon changes the product layout very often and heavily conducts A/B tests. I’ve once even heard that computer vision is the most stable way to scrape Amazon. I guess this library will stop working rather soon.
At a former employer we scraped Amazon many millions of times per day with very simple old tools that rarely needed updating.
For example, Scrapinghub's Crawlera (the guys behind the Scrapy python lib)
I have not scraped a ton of actual individual product pages though so cant testify about scraping that. I do remember it might have been harder.
Don’t really see that as a dealbreaker. So the library will need maintenance. Normal for libraries to need updates in order to keep up with changes. It works today, and it will work whenever it’s updated. Better than nothing and for many use cases that’s good enough.
What's more difficult is product page scraping, because there you have hundreds of different variations. Some from A/B testing and a lot just being specific things that show up for certain product categories (e.g. video games).
