If I buy a $100 projector vs a $1,000 one, or a $20 curling iron vs a $200 one, the order of magnitude difference does make for a better product, I find.
Yes I agree that there are better products for more money, it's just that I have to filter by something else because I can't trust that the price corresponds to performance for any given listing.
I don't believe you. Link? That extra $900 gets a iot more lumens and portability and CPU and ports and such that the $100 ones I've seen just don't have.
The point is that if you go to a store or Amazon, you can find crap products at any price point, so much so that you cannot look at the price to get any information about quality.
