jeffnz:networkn:jeffnz: sorry for all the posts especially if you guys already know all this but just in case.
I was looking for a battery cover and came across the following , I have dealt with Aliexpress before and they are ok and its free freight.

If you search the site they have the flip cover ones with the window as well
I bought these in dark grey and light silver, and I do like them, though they scratch and the logo is raised and will scratch very soft surfaces. Makes the phone feel more chunky. Unsure if I will keep it.
ok thought they might be like that but its just a cheap way of protecting the back, I did get Plastic ones for S3 and they were ok but did eventually break but we very cheap.
They do look really great though.
