“We couldn’t be much happier with the OPI system. If we could we would put every bin that we have on the [OPI Blue] system.”

Jonathan Wheatley 

“We have found a couple of hot spots already and if you ask me that is slicker than can be because you can check it anywhere you want. I can check it from my phone, so I check it at home now and I even checked it when I was on vacation in Mexico which was neat.”

Sean Befus 

“It sure is nice to rely on the OPI system. Especially with the canola. It is a lot of money in that bin and it is nice to be able to sleep at night.”
