Good Quality
I'm really happy to have one and I need more... but unfortunately it's very hard to find OMEGA products in IRAN

Omega D8400
Reliable DAQ. Just a note that it the software to configure the Channels is not easily or readily available, and there is no manual that goes to explain how to use the software
