There are many reasons not to buy Darth Toaster. It's an average performer in bread toasting, it can't fit bagels in its slots, and it's not the easiest model to use. If you have a significant other that doesn't like Star Wars, then you probably don't technically have permission to buy this model. But if you're just drawn to it, if you are enticed by the undeniable twinkle in Darth's eye, if you cannot resist the pull to the dark side, then, well, you cannot escape your destiny.
The same company also makes a Star Wars Stormtrooper Toaster. It's a great addition to any Star Wars fan's countertop, though it is susceptible to Jedi mind tricks.
