I have a GLM flipper board on the left side. When you get them dialed in, they work well... they are just extremely finicky in getting them set up. Recommended electrical tape worked horribly for securing the magnet for me. Oddly enough, scotch tape worked on the first time I tried it. I then put a strip of electrical tape over the scotch to make sure it didn't move. I also have to pad the shooter bracket with something because on hard flips the magnet board will hyperextend itself and attach to the bracket, which completely ruins a game. I may someday return to the original board if I don't get that straightened out.
