I have barely used it since buying; the packaging and the product are as good as new. It came with a clip for wireless-supported phones which is missing, but otherwise, there are no issues. It gets so cold that water droplets form on the top within one to two minutes of use. You can buy a clip from the market if needed, or those with wireless-enabled phones can use it directly.
