However, the beep when putting a device on charge is incredibly annoying. Especially with the style I use this pad. I use my phone, text, call, browse, then put the phone back on the pad so I know I can leave at any time and the battery will have a good charge. So having an insanely loud beep each time the phone is placed on the charging pad is not ideal. And is also why I stopped using it after just 4 hours. When I get some spare time I will be opening the device up and ripping the speaker out of it. Thus making the device work well.
I can confirm reports of other people getting alot of radio interference from this device. Normally a sign of cheap electronics used inside. If you have any wireless communication devices around where you want to charge your phone this product is not for you.
