The Little Squeeze, a small and powerful can compactor made by Bee Cool Manufacturing, is absolutely perfect in this regard. Small enough to store in any area that can accommodate an average-sized tool box, it's lightweight and flexible enough to be rolled out when you need to put it to use. With the powerful hydraulic ram that does the actual compacting, the Little Squeeze has four tons of crushing power.
Because these are perfect for professional garages and enthusiastic home auto body technicians, many auto supply and do-it-yourself stores are starting to carry crushers and compactors. The Little Squeeze is perfect for this type of user because of its size, ease of use, and low price. Other crushers are gigantic machines on the scale of a dumpster-sized compactor. These are impractical and expensive, unlike the Little Squeeze.
