I remain doubtful of the efficiency of this stainless steel screw twist lemon juicer, but it certainly looks neat. I'd worry that I wouldn't be able to get enough juice out when I needed it, while still dealing with a constant slow drip.
Of course I will remain an idle wonderer about such matters, because it sells for a ridiculous $40. Do you know how many lemons you could buy for forty bucks? All of them.
