Like the Holga, this is a simple plastic 'lomography' camera with a fixed focus 50mm lens. The shutter speed is fixed at 1/125th second and there are three apertures selectable (f/6, f/8, f/11, f/16). It gives similar image quality to the Holga - in other words, light leaks, fuzzy edge definition, but a lot of great character.
