Typical and cheap light meter, for this price don't expect anything special, it won't give you 100% accurate numbers, however it is a simple light meter with a deviation of about ±5%. For simply taking approximate measurements it is very good, always for its price, generally I would say it is quite a value-for-money product, the only negative is that it doesn't have a backlit screen, which personally doesn't bother me that much

I bought it so that I can control the light sources and have an estimation of the existing light. I will also use it for photography and I will come back with updated impressions.

It works fine, wonderful. I bought it to conduct an experiment, to see the relationship between lux and the camera's exposure, and I found that if you set the indication to Fc for the shutter speed and aperture 2, you have the correct image capture, meaning the correct correspondence.
