I ordered this car charger to use with my Sony Ericsson Z500a wireless phone. I thought i was getting a great deal b/c the price was so low. However, the plastic prongs on the charger are a different size than on the charger that came with my phone. With a little effort i was able to plug the charger into my phone, But I had so much difficulty removing the charger from my phone that I feared I would destroy my phone. I will not be using this charger(lest I should destroy my phone)and have wasted my money when I thought I was getting a bargain.
