For me it was “buy high quality pillow” because you sleep for one thrid of a day etc. I needed a new pillow anyway so I came to the store and bought the best they had. And it was … ok. Like it’s a fine pillow but my sleeping haven’t improved really, it’s basically the same. So I was disapointed :(
So, which life pro tip disappointed you?
Hand tools are fine 99%. Cutting tools–the part that actually does the cutting–are usually fine. Power tools are very hit or miss. Like, I would definitely not buy any cordless or corded tools there. Air tools are generally okay, but don’t work as well as other, more expensive air tool brands. OTOH, I’ve used a Harbor Freight flooring stapler that failed in under a day of use, while the Husky branded stapler did just fine for a few years. Impact sockets are good, although they’re limited on sizes (I don’t think that they have anything bigger than 22mm). I’ve been using a Harbor Freight floor jack and jack stands for a few years now without issue.
