Hello, I guess you mean fantastic, and not "frantic" 😉
Well, over the years I've owned 5 of these cameras, they are more or less minor variations on a theme, and 2 have survived - two Minox 35MLs. These are also (just about) the only Minox's, save for the most recent couple of models (which are very expensive new) that take easily available batteries.
The other three all died a sudden death from the "non-opening shutter problem" that is common with these cameras (something with the shutter electromagnets - some people claim they are easy to clean and fix, but I tried opening up one of my dead cameras and quickly lost some tiny pieces that even if i found would be difficult for me to put back correctly...)
The 35mm lens on all the Minox 35 cameras I've owned has been just about as sharp as anything else I've used (Leica glass included). The meters have always been reliable, BUT THE MINOX 35s ARE NOT SUITABLE TO USE WITH FAST FILM UNDER DIM LIGHTING CONDITIONS - with 1000 ASA film, the shutter will not stay open for longer than about 1/15th of a second no matter how dark it gets. With slower film, the shutter will stay open for longer times under dim conditions.
I usually use my Minox 35ML with Tri-X at 320 under more or less normal daylight conditions.
The cameras are capable of taking great photos, but unfortunately, due to their reliability problems, I wouldn't trust one as my sole camera on an important trip - so if I now have to carry two, why not just use my Leica M4-P already? So, yes, I don't use mine very often anymore, since I have several other great cameras that are more study and realiable and that I can use day or night (or that have manual controls). But none of those cameras are as small and light as the 35ML.
Anyway, you can get these Minoxs pretty cheaply now, so i would just find a "live one" and give it a try. Focusing is by estimation, so make sure you can live with that before buying. I find the 35ML great for discreet shooting as you can focus without bringing the camera to your eye, AND IT IS MUCH QUIETER THAN ANY LEICA.
Good luck and enjoy it if you try it.
