The Black & Decker CitrusMate Plus BJ625 (*Est. $20) is an electric reamer that spins under its own power, reversing direction automatically to squeeze every last drop out of citrus fruit and drawing high praise for its efficiency from one expert review source.
The BJ625's adjustable strainer, which lets you fine-tune how much pulp makes it into the juice, is a big hit with owners and users alike, even though it's made of plastic and the motor needs time to cool off periodically when juicing high volumes. The BJ625 earns much better ratings for durability than the metal Amco Houseworks enameled citrus squeezer (*Est. $10), and Metrokane L-Press citrus juicer (*Est. $95), both of which are manual juicers.
Reviewers love how the Amco citrus squeezer feels in their hands, but we found a number of recent complaints about the handle snapping upon first use that we wonder if there's a quality control issue. The Metrokane L-Press's steel-and-aluminum body flexes so much that it leaves juice un-squeezed, and eventually deforms -- or loses critical parts -- and stops working.
Both of these manual juicers are also finicky about sizing: If the fruit doesn't fit into the juicer just right, it'll be squashed into mush or only juiced halfway. The Black & Decker BJ625, by comparison, juices citrus fruits of any size. So does the Oxo Good Grips Citrus Juicer (*Est. $15), a simple manual reamer that requires more effort but doesn't have moving parts that can break or overheat. However, we found complaints that the triangular cutouts in the Oxo model tend to collect pulp (and thus waste some juice).
If you want the absolute most reliable citrus juicer you can find, there's almost nothing that can go wrong with a simple reamer. Made of wood, plastic, glass or metal, these handheld tools are readily available and relatively inexpensive (as low as a few dollars in some cases). Reamers have no moving parts or juice cups to break, just a ridged cone to extract juice; the trade-off for their reliability is the amount of time and effort spent making a glass of orange juice.
