I’m Michael Chen, a former engineer at a consumer electronics laboratory and also a father who once bought the wrong air purifier, causing my child to have an allergic reaction. In 2019, my original intention of founding EvalMaster was simple: to use an engineer’s mindset to solve the problem of consumer decision – making. 

Our working methods are somewhat special:
✓ 226 – hour single – product testing cycle: From coffee machines to robotic vacuum cleaners, each product needs to pass 27 laboratory – level index verifications.
✓ Double – layer filtering mechanism: First, the algorithm screens out products with a market negative review rate of > 15%, and then an 8 – person evaluation team (including industry – certified engineers) conducts blind tests.
✓ Dynamic tracking commitment: All recommended products are continuously monitored for real user feedback. If the score fluctuation is > 10%, a re – review is automatically triggered. 

You will find three major differences here:
① There is no “Editor’s Choice” list. All ranking data comes from the 6 – month experience tracking of more than 3000 real users.
② Each review comes with a “Defect Microscope” column, objectively presenting more than 3 product shortcomings.
③ The structure is in the form of a NASA mission briefing, and key indicator comparisons always appear within the first 90 seconds of reading. 

In the past three years, we have received 1372 reader emails saying, “Finally, I don’t have to switch back and forth between 20 tabs anymore.” This is exactly the value we uphold – to bring consumption back to rationality and let choices respect time.
