Yes, easy to install, maybe require a bit of bending of the struts to get the perfect fit for your bike but easier than full guards.
Once on, very easy indeed to remove and put back.
Worth protecting the frame where they go on - they come with a patch of clear tape to stick on the fork/stay to protect against rubbing : I'd actually put another couple of layers on - clear tape, electrical insulation tape anything like that.
The back one's fine, but I found the front one a bit short - go though a puddle and half of it could dump in your shoe : this fixed easily by pop-riveting a piece cut from a fabric softener bottle to the bottom.
