I do not comment on my article that I sent immediately without testing. The switch system for which I chose is also a ATEN, it perfectly fulfilled its role. In terms of the brand, I have no complaints. The model that is mine is well designed, robust .... fully functional after more than a year of daily use. I also material of this type at work, ATEN brand also, very very very busy every day, still perfectly functioning several years after installation. ATEN, eyes closed for me
