Query: Sony Ericsson Z500a

The following review is for the Sony Ericsson Z500a, and has been composed by one or more person(s):The Sony Ericsson is only a good phone for those who do not plan to spend very much time on their cell phone. This particular phone by Sony Ericsson, is definitely not their best! The maximum time this phone will hold the charge is approx. one hour. Therefore, if you intend to purchase this phone you might want to invest in a car charger also.If you are buying this phone because of the camera feature, it is highly advised you try a different phone. As they say you get what you pay for and this is a very cheap phone with little value to wireless communicators.This phone has, on more than one occasion and with more than one person, shut off and/or malfunctioned for no apparent reason. The overall rate for this phone is a stunning 61.3%*!*This percentage was obtained from an online source.
