Metrans Qi Wireless Charger Wireless Charging Receiver for Samsung Galaxy S3

Comment:
Very easy to install. You simply take the back cover off, pop it in and you are good to go. (It has double sided tape so you can attach it to the battery).Charging off of a Qi charger works perfectly.Oh, and if you are wondering, this is only for the Qi receptor. You need to buy a Qi charger separately.The claim is this hardly adds any height to the phone and doesn't require a special back cover, which is true, but the extra lump is definitely noticeable, especially when the phone is naked or is in a TPU case.It is impossible to notice this lump when the phone is inside a heavy duty case, like an Otterbox commuter.
