Review on Ultrasonic UV Sanitizer Professional Eyeglasses by Carlos Phillips

I used the UV-C test card to see if the sanitizing UV light was working. It's hard to tell because UV-C light is invisible to the human eye. After leaving the test card in the cleaner for a full 5 minutes, the UV-C button turned green as if it was working, so the letters UV-C on the card should be lit, NOT DONE, meaning the disinfection has NOT HAPPENED . on the. This is really bad as people who buy this cleaner rely on disinfecting all sorts of things like masks, phones, pacifiers, goggles, etc. My test card glows in the UV-C range from 250 to 270 nm UV-C light. This cleaner is rated at 253nm. It is therefore in the luminous area of the map. I will contact the seller and update this review when the issue is resolved. UPDATE: The seller was happy to send me another cleaner, but I tested it and it didn't register any UV on my test card either. I wouldn't recommend buying it unless you have a chance to UV test. Test cards are available from Quantadose's Revain here.
