I suppose it is OK for a mouse to come with a built-in calculator, but it really is pushing it when it comes to the MSC-500 Mouse Scale that – you’ve guessed it – features a built-in scale the moment you open up its outer shell. This integrated weighing scale is made from stainless steel and measures 2.25″ x 2.7″. What makes it interesting is it is able to operate independently courtesy of its internal USB rechargeable battery. Weight readings are read in increments of 0.1g, 0.005 oz., 0.005 ozt., or 0.1 dwt. Guess it is now time to play the part of a coke dealer in the office, eh? Small price to pay then considering American Weigh is asking for $59.95 for the MSC-500 Mouse Scale.
