If you want a small digital camera separate from your phone, it’s probably fine. The problem is that mid range phone cameras have comparable quality, so most people are better off spending £40 more on their next phone than buying a £40 camera. As a result of this reality, these sort of cameras aren’t in high demand, and don’t have many options available.

If I wanted a camera separate from my phone, I’d probably save up for a DLSR or film camera, as I’d get better pictures and more out of the experience. However, if you absolutely must have this type of camera, I won’t stop you.

Not a rip off, but if you have any second hand/thrift shops near you I think it wouldn’t be too hard to find something like this for <10£. If it turns on, takes a pic, and is not visibility broken it’s good, they don’t really degrade usually (until they die completely)

If you plan to use it and you can afford it, sure go for it.

Use it and keep it out of a landfill

Just don’t forget to have fun with it!

EDIT: Also I’m not sure what kind of batteries it has but be aware that the older it is the more likely those batteries are to be difficult to find but also more likely to be not great condition from hello. Unless it takes some kind of disposable battery, in which case you’re likely fine. Or if you have the confidence AND skills to make a new battery for it if need be.

Good? No idea. Necessary? Most definitely.

Call it gender affirmation. It’s medically necessary. Bill it to your insurance or something.
