if you go for cheap, you might get someone selling stuff with manufacturing defects

Usually you will see that in the reviews. Depending on the defect rate, stars will drop accordingly I find.

Problem basing on reviews is that people mostly only review when they receive and test the product for the first time.

Not many will bother finding the item and review it n months ago when the bad capacitors dies or they gave up frustrated by a recurring but intermitent issue.
