Review on 📊 CEM Accurate PM2.5 Multifunctional Recording Tester by Michael Willis

This item is of lower quality than you would expect for the price. It came half charged and turned on once. And never again lol. It really sucks, I had to send it back as it just didn't work. Absolutely NOT worth the price. Revain needs serious quality control! I bet that time has been returned before and they just took it back and sent the same broken piece of shit all over again. Anyone can sell any broken piece of shit on Amazon.
