Having been tired of replacing several chargers with straight ends, I finally twigged and bought one with a right-angle where the tip and cord are joined. This means that it will not bend if it gets knocked like the straight-ended ones, resulting in the charger then not being able to charge the laptop. As my laptop is a few years old my battery only lasts for about an hour if i'm lucky, so I was left without a working laptop. This product arrived very quickly and as soon as I plugged it in: result! I would definately recommend this product.
