Does the price determines how the product is?

Paying the extra for trustworthy brands almost always the right idea. But paying more for one good brand than another, doesn't really make sense. For example: Buying a Sony TV that costs $300 more than an identical Sharp TV. (I just used Sony and Sharp for example. I don't actually know ow much they cost in comparison).

That being said, I bought a cheap 19'' HDTV (I can't remember exactly how much it cost) made by an unfamiliar company named Blu : Sens, and it has worked great since I purchased it. (About a year ago).

This is the best picture I could find of it...

Most of the time that statement is true, but other times it is not. Things like food, batteries, cleaning products, and all that kind of stuff usually work about the same even though the price differences.

And some things like headphones are not much different from the about $10 to $30 range.

And then other things like HDTV's and cameras you get what you pay for.

It really depends on what you are buying.
