Can you review a product not for its intended purpose?

So for example, there are rolls of clear tape for your skin. They're listed as being for tattoo healing, but people use them for all sorts of other stuff like covering medication patches so they don't fall off/are waterproof.

So if I'm using it for that, but still review it as the tape itself (stays well, easy to put on, non-irritating, good price, etc), is that ok?
