Good MFC but poor customer support
Beware!! they don't sell it with power cable so make sure you buy it! The technical support person is not thorough and will try not to understand your needs. The return policy is also not good. However, it is a good MFC with precise control.

Mass flow controller
It works great, very sensitive. Seller should provide a adapter with controllers to run

Love them
Great MFCs at a quick turn around, we use them in many applications. Some times in multiple flows.

Difficult to work with and incomplete manual
Mass flow controller is not functional with shop air.
