1 of 1 people found the following review helpful By elementai (Moscow, Russia) - See all my reviews Amazon Verified Purchase( What's this?) This review is from: HQRP Color Charm / Keychain UV Radiation Meter / Tester for Skin and Eyes Health Monitoring / Solar Ultraviolet Radiation / Ultraviolet Sunlight Detection (Health and Beauty) Fairly simple device, and it works. Don't expect much from it, UV readings aren't very accurate depending on brightness, viewing angle and personal color perception.Bottom line - a good item for it's price. |
