Depends on where the gun is. I've talked to a lot of people who complained no one used it so they pulled it out, but those guys put the gun holder at the farthest back corner across from the meter box and HP gun holder. I put the gun at the same end of the bay opposite the meter box and gun holder, and about a third of customers use it because they have to pass the gun to get to the foam brush and they can see and hear the trifoam gun when they select it.
