I think they are awesome.  My cats are do not.
These cat scratchers are well made of high quality plastic.  My cats were happy when I used it to “brush” them a bit.  I placed them in two of their favorite spots to rub on.  I didn’t see any way to get the enclosed catnip to stick so I tried my catnip spray.  My cats have no interest in these.
