I guess I'm in the minority here as I've had games on location for several years now and had zero problems.
It really depends on what kind of location you put them in and your relationship with the location owner. I have a few of mine in grocery stores/bars owned by my family and a coupe of others in local pizza places close to my house.
Except for a monitor needing a rebuild and, most recently, a Pacman board needing a rebuild (after going strong for 3 years), no real problems. The games are well-looked after though by the location staff and I don't have anything super valuable out there, so there's that.
Basically any common stuff i get for a deal, and i have a place for it, I'll put out. I do make a couple to a few hundred a month all together from the locations, but that's because I don't have to cut the locations in on the take. [emoji4]
I have one pin in that mix of machines and I will say that's a pain in the neck to keep running perfectly sometimes.
Machines that I have out there and the breakdown (if anyone is curious or cares):
Star Wars Trilogy pin
SF2
Original Pacman
Track and Field
Original Ms. Pacman
Neo Geo 2 slot
Arkanoid cocktail (in a williams CT cab)
The SF2 and pin are in one family owned location, the Pac in another, and the Ms. Pac in another. The Arkanoid, T&F, and Neo Geo are in separate pizza places in town. The Pac makes the most money and the T&F makes the least. I have MS2, Baseball Stars 2, a rally race game i can't remember the name of, and Puzzle Bobble in the Neo Geo.
