I use it for 1 year.
It is not expensive.
I have other models which seems more pro .... for not more expensive ....

Connections chaotic home ..... 250 block but we add support harting, and decision 380V. Otherwise, it is guaranteed, the internal terminal block is super sensitive! 3 connections and everything is dead.
feedback, have to be the reason ....
Once harting quip, a 380V cable set and fly, was more pro

The manual mode with 4 buttons is incomprhensible in live mode, but very convenient for testing without a table.

A good small block for fun.
