I received the item very quickly, well-packaked, in perfect condition. The device works very well, I am very satisfied. Thank you very much!
It is not a professional product! The socket in which the tester is mounted are 231 V and it shows 265 V (?!). It can be used as a tester without displaying the voltage - the tester works. I ordered it to stop measuring the voltage with another device. I have nothing to blame the seller. The product arrived quickly.
