If you think its a must, then go for it. But if you close your macbook, I suggest taking it off first. As what other members mentioned, it does really leave a mark on the screen, and I found it impossible to fully remove. I used to have a generic one, which I got for 200 pesos I think, then I found it uncomfortable to type as it was too thick, so I purchased a branded one, moshi to be exact, it was thinner and more comfy to type at. But I like my keyboard as is.
