I have researched all the threads but only find people buying and complaing about the replacement. i was at walmart lat night bough the rainx. blades 24in and 21in. went to install then today and the stock blades have this plastic clip you need to pinch to remove them from the car. Now does that plastic pieces remove from the blade or is that was the big complaint is about that it is all one piece and the reason to purchase from the dealer please let me know. my wife is about to take a 1100 mile trip. thanks.
