are cell phone skins worth buying?

If you don't mind your phone getting scratched, then no.
But since you said your phone is kind of bland, you should look for cheaper alternatives if you are worried about spending $20.
Skins like the ones you mentioned are of higher quality and will not leave your phone sticky. I believe that they should be fairly easy to put on.

Hope this helps!

they are worth buying, you get the sticker make your phone look nice, its much more cheaper than buying a brand new fascia. i have one for my k850i it looks really good and it doesnt get sticky when you take it off.
