EBay is a global website and I listened from many people's that is very good , but when is used it and ordered some thing it didn't find it as I was expecting , here are some reasons
Customer service - some days ago I was put on hold for 10 mins and got disconnected , I found this very annoying.
Product quantity - product quality is fine , but sometimes seller doesn't look genuine
Delivery time - I ordered one bag and didn't receive on time
App and websites works fine
Reliability - u can be reliable on eBay but not on seller they have , they don't look genuine .
Thank you
