Regarding the reliability of the red lion g3's. I have several that have been working for years in a washdown environment with a very harsh sanitation crew. I also have about 20 in dry environments. All the ones I have touched in washdown environments have been flawless. I have replaced a few in the dry after 10+ years of use. I havent ever encountered one that outright died. Everything I've seen is backlight or LCD issues.
I have developed for red lion g3, panelview, and panelview component. I, by far, think the red lion software is the best hmi development software I've touched. I have proface and Mitsubishi software on my short list to touch. Honestly if it can be done, I feel I can do it better and faster on the g3.
