Anyone tried them? I'm really intrigued by the prices. You know if it seems too good to be then it probably is.

Mostly talking about

They even have pads with the cooling fins.

The pics look great, no I have not tried them. But more than that I have no clue to the aliexpress, that is what I would investigate first.

Watching another video that compared some breaks, they claimed by their tests that the 4 piston wasn't even as important as the size of the rotors. This is really intriguing to me now.

2 piston with 180mm rotor was very close to 4 piston with 180mm rotor.

Guess this kinda kills the dream for me now, but I think I still gotta feel it for myself.

Although I love online shopping because it is so convenient, I am still reluctant to purchase any safety or security products from aliexpress such as brakes. I don't know if any certification markings should apply.

Hi Jeanne and welcome!

Technically, anything (I believe) that is sold for importation into the US has to pass the federal safety regulations. If that actually happens, I don't know. That doesn't mean your are getting a quality product that won't fall apart, only that it has initially passed muster to be sold here and that could apply to a domestically made product also.
Back in the late 70s, the CSPC added changes to the requirements for bicycle designs in regards to safety concerns. Many think it was merely a ploy to help the domestic bike market and to just make it more difficult for the European and Asian manufacturers to import their products, thus increasing the domestic market share. Unfortunately, it was enacted just at the end of the "bike boom" and didn't really affect most manufacturers who distributed worldwide. Some of those "safety design features" are not longer applicable so it became obvious that the changes had nothing to do with the actual safety of the bike in the first place.
Take care,
Jesper
