Beautiful small and light instrument. Quite a solid construction. It has non-slip rubber on the sides for protection and good grip. The package contains a very good hard protective case with soft material inside. The screen is relatively good and legible indoors but is not a touch screen. Outdoors with sun you can see the indicators by adjusting to greater brightness. However, the graphics bar is absent as in other instruments. It seems to be working properly. I hope the G-M lamp lasts for a long time. Unfortunately, I do not have another instrument for measuring accuracy to be able to compare it. The battery was discharged to 0% I connected it to charge quickly rose to 25%. Compared to a relatively good value radioactivity meter, however, it could be better if the screen was touch and had a graphic bar indicator as well as if it supported data transfer to a computer or mobile phone through a suitable application. Thanks Banggood.
I think, this is a quality product. - good materials, soft touch and design - very bright and high contrast LCD - good battery , 18hrs of measurement,and its still close to full (Check photo) - easy menu navigation - loud warning sound - strong clip on backside. - high quality hard case - nice users manual (the tool is orange/black, my mobile camera made it yellowish on photos)
