PC Sports Games heeft een review van de Gravis XTerminator geupt. Hier een stuk over de performance van deze gamepad:
I have nothing but praise for the performance of the Xterminator. The gamepad performed extremely well in every game on which it was tested. It is at its best in sports games, such as FIFA 99 and NHL 99, which require a variety of button combinations. The comfortable design and efficient layout allow the most complicated maneuvers to be performed with relative ease. Of all the hours I spent on the Xterminator, I experienced very little hand strain from even the most intense gaming sessions. This, in my opinion, speaks volumes about the brilliance in the overall design and performance of the product. The only area in which I found the Xterminator’s performance to be less than ideal was in racing games.
