About Quang Sang

Quang Sang publishes one kind of page: a set of products laid out side by side in a single spec matrix, with one pick at the top. There are no categories and no tag pages — just the index, newest first.

Where every number comes from

Each figure on this site is one of exactly two things, and the page labels which:

• Spec — a manufacturer-published figure, reproduced as published. If two makers state the same property differently, the table shows both forms rather than silently converting one.
• Hands-on — something observed while using the product, described in words rather than digits.

The score out of ten is editorial judgement. It is an opinion held by one person, not a measurement and not an average.

What this site is not

It is not a laboratory. There is no test bench, no instrumentation, no calibration procedure, no certification and no staff beyond the byline. The interface borrows the vocabulary of instruments because that is a good way to read a table — not because any of it was measured here. Where a comparison would need equipment that does not exist here, the article says so instead of estimating.

Who writes it

Builds the comparison table first and writes the article from it, so the numbers and the recommendation can never drift apart.

Corrections go to hi@quangsang.online and are made in place, with the article's updated date moved.

How it pays for itself
