A little tricky to screw on to my Canon 1000D - but once it catches I just leave it and it stays in place. I mainly needed it to photograph small rooms. Yes, there is shadow on the edges if zoomed in completely, but it's a good bit of fun kit for a really good price.
Tried this after a farm owning friend recommended it. Have been trying to get rid of mice in the house for a couple months with regular Rentokil. Used this and in just over a week our mouse friends were gone.
This is my second of these cases! Okay, they don't last forever, but at the price I'm fine with that - it lasted about a year for me and I'm very nonchalant with my iPad. The hard casing has prevented corner damage from a few drops. But mostly I love the turning back handle - great for showing images or videos to clients and people I meet. Also makes holding it for reading eBooks much easier. The newer version that I just bought also has ribbon so you can use the back as a stand - great addition! (previous version had no ribbon so when the folding materials got too flexible it would just fall over)
