The majority of the razor is made of injection molded plastic, except the top of the head which is cast metal. It appears quite solid - at least as solid as most cartridge razors and much more solid than most disposables. It is a two piece design - twist the handle and the metal cap comes off. The mixed construction is well balanced, with the center of gravity shortly below the head. This makes for an easily maneuvered razor, while keeping it so light you hardly notice that you're holding it.
Comparing it to another cheap razor - the Yuma - I would say that the Racer feels less harsh but is more aggressive. It's not a bad razor for a newbie on a budget - provided s/he is told to be careful and to make sure not to use any pressure. Combined with a good blade it gives a more than acceptable shave. It also is a decent second razor for a more experienced traditional wetshaver, perhaps as a semi-disposable travel razor. All in all I can recommend the Racer razor to, well, anyone who fancies a very cheap razor for whatever reason - just keep in mind that there is many better razors out there, if you're willing to invest a bit more.
