- Simply the best! Review by Graham
ProtectionRecently received the Quattro 4 case as part of my "SmartCase 4" order. Just awaiting release and shipment of the battery pack. I have various other iPhone 4 cases and all I can say is the IvySkin product has been very well designed and the build quality is first class. It is also extremely comfortable to hold and provides a superb level of protection for the iPhone 4. Follow the installation instructions properly and I can guarantee there will be no need to use any other case again. I will definitely order an additional battery pack when they become available. I was specifically looking for a case for general and prolonged outdoor use where good protection and the ability to change battery is essential, especially with the GPS navigation software I use on the phone whilst outdoors. Many thanks IvySkin!
