It is the 2nd G350J. The first was installed in 2019.
I didn't found any issue about mechanical part on the 2nd G350J(the first G350J has many mechanical problems). Much improvement during 3-4 year.
Electrical and control parts are superb ans same standard as the 1st G350J. Smooth and reliable performance.
Human Machine Interface(HMI) is not beautiful but workable. Better if improvement about English translation and amend some wrong spelling.
In conclusion,I am very happy with the 2nd G350J.
