That's the one I just received last night. It's a nice fit indeed but I haven't actually used it yet (will do later). Initial thoughts are that I like it a lot, and will also experiment with a front magnet, if I can. Let me know how you get on with that also, I'm wondering where I can get a very slim magnet of the right size to have a go with? (to make it sleep/wake-up, on demand)
At £4.99, it's a steal!
