I've had the Surge for a week now and it works great. It adds a little weight to the Ipod Touch but fits comfortly in your hand. There haven't been that many sunny days so it takes a while to get a full solar charge. It doesn't take long to get charged when hooked upto my PC using the supplied USB cable. No problems sincing to Itunes. Only problem is that the hole for the auto out plug is too small. Works only with my earbuds but not with my earphones or external speaker. No problem when using Bluetooth or WiFi, in fact I am posting this using the Blogger app over WiFi. My rating for the Surge is 4 stars out of 5 cause the phone plug hole is too small.
