Find out the size and amp restrictions before you look for a unit. Many schools require 1.6 amps or less and 5.0 cubic feet or less. Additionally, check the room size. You'll want the largest unit allowed that fits in the space you have, and if your roommate is bringing his own, you may want to forgo the unit entirely. Two fridges take up too much space.
Look for the energy star rating. While you may not be heart-broken if the school is dishing out extra dollars to run your Microfridge, they are handy units to have at home and you'll want yours to be as energy-efficient as possible. Also, buying with an eye to its energy rating reduces your carbon footprint.
