Product review (1 stars): Customer service won't help me.
There were no instructions for mounting the tower over a countertop and the company could not provide me with any. It came with 3.5 inch screws in a bag with nuts and washers. Inside the unit, around the hole for the tower is a plastic ring with 4 holes. So with the lack of instructions and with all indications that you're meant to put the screws all the way through and secure with nuts and washers, I attempted to do so. It turns out that I wasn't supposed to do that. After threading all 4 screws loosely, I looked inside to find a mangled mess of plastic caused by the screws. I guess the thread is fine enough and the plastic soft enough that I didn't feel any resistance. Even worse, when backing the screws out, insulation must have gotten in the threads and siezed. To get the screws out I had to use a bit of force because it wouldn't budge either direction. Then the female threaded piece broke off in between the inner and outer shell of the refrigerator and the screw and washer is just spinning freely with no chance of me ever getting it out.

Customer service was nice but wouldn't help me whatsoever. They couldn't even send me replacement screws claiming that the version of my Kegerator is no longer being sold. The model is br7001ss.

So beware of the installation. If you get the same 3.5 inch screws, you'll have to cut them to length I guess and throw away the nuts and washers. Don't do what I did. Or buy one from a better company.
