The one thing that did surprise me when I got the camera was the lack of a lens cap for it. The viewing lens is no lens at all, just a piece of plastic. But there was no type of lens cap for the actual lens. Not really a gripe, just an observation. I have shot toy film cameras since I was a kid and most of them did not come with any lens caps either. I did find an old, padded lens pouch in my junk box that the camera fits in perfectly, avoiding banging around in my camera bag.
I did notice that the B&W jpgs are warm, like a slight sepia tone. I prefer a more neutral or slightly cooler tone, but these warmer jpgs should be fun to play with. I am a firm believer in working with whatever a toy camera provides. After all, it is a toy camera- let it act like one, warts and all. It is simply a matter of using those quirks and warts to your advantage to produce some really cool photos. I shot a Holga lens on my m4/3 cameras for years and some of the best photos I got from my m4/3 system came from using that cheap, 15.00 Holga lens.
I have been downsizing the past few months and my extremely small, everyday carry bag now holds four compact cameras- a Camp Snap toy camera, the newly arrived Cuzhao toy camera, a Lumix LX100, and a Ricoh GRIIIx.
