This is an easy-to-use, simple rangefinder camera. I've run several rolls of film through it, and I haven't noticed any major discrepancies in the rangefinder or shutter speeds (this is subjective). The double image is easy to see. The shutter speed is off by only one second; it's between 1 and 1/2, so it's roughly one second. The shoe is bent, so if you want to attach an external viewfinder, you'll need to modify it with pliers or something similar. Image 6 is a reference photo taken with this camera using expired film. Please purchase only if you understand that this is an old item.
