A little over a year ago, Lofree burst onto the scene with a quirky, colorful, vintage-inspired mechanical keyboard. We loved it. Now, the brand is back with another retro-looking device, the Digit Calculator. Built with similar round, playful buttons, the Digit Calculator begs to be used. And like the keyboard, the mechanical switches offer a tactile and responsive experience, so you’ll get somewhat addicted to using the device. The display screen is tilted 6° for better visibility and the whole unite rests comfortably on your desk so you can punch away without it tipping and tilting. Each runs on a single AAA battery and offers 500 hours of use before you need to swap that Duracell out. You can back the quirky calculator on Kickstarter right now.
