Do they work? Not sure what you mean but you do need a whey shake for PWO its very important.
All shakes are for is to SUPPLEMENT you diet?! Most people say 1 to 1.5 grams of protien per lean body mass and if you are 230+ this can get difficult with whole foods.BUt a shake alone isnt gonna do wonders it will only help you along with a good diet plan.
But yeah is is a god idea to get some whey for your PWO besides that if you can get all your protien in then you dont really need any other time.
