I ran into these on the internet, and am intrigued by the flexible I/O mix, reasonable price. Does anyone have any experience with them?

 

I used their PLCs for several differnet applications.
Several process machines- plastic injection
Industrial heater control
Ammonia refrigeration control systems
Developed a control system for a sub of Raytheon,they needed to have redundent systems for a radar cooling system. Entertron was able to
modify their software to allow communications with some specialty military hardware, ask the big boys to do that.
My overall experiences were good and profitable
