Review on RCYAGO Radiation Illuminance Luminosity Measurement by Seth Singh

Can it be improved with things like backlit display, battery level indicator, strap, smaller size etc.? Well, to be honest yes, but for a cheap counter this is the best. The measurements are reproduced by my laboratory measuring device. It seems to me that accurate and repeatable readings are all most users want, and this product fits that bill perfectly. I can't buy anywhere better.
