Proof of Usefulness Score
Lab Mode

The submission describes a defunct hardware startup (Magic Instruments, YC W16) while categorizing itself as a review blog, indicating a repurposed domain. The claim that 'most people have used my product' is factually false and represents a significant red flag. The original company is inactive/acquired, and the current website appears to be a generic affiliate content site with no technical innovation or unique utility.
