by Ciara K on Jun 1, 2010

The calculator was great it helped me greatly in my electrical engineering class linear system and signals. I would definetely recommend Graptor services to anyone. When I needed a calculator and couldn't afford to get a brand new one I rented for a good price. It was my first time using TI 89 Titanium and I must say it has been the best calulator I have ever used.
