Grillr is an electricity-free, wind-up, and portable rotisserie oven that lets you cook BBQ anytime and anywhere. Simply wind the knob to allow for 360° rotation cooking. Grillr runs on a small butane fuel cartridge that is much more affordable than large propane cylinders. Maintaining Grillr is super easy; it built with sturdy and delicately designed springs that last for a long time.
