These work perfectly! The iPod touch fits very snuggly into the dock with these, which I was suprised at considering the curved back. I have an Apple universal dock which this works perfectly in, and also a Cambridge Audio iD10 which this also fits into.
They are really well made; thick solid plastic. The only way in which it could be made any better would be if Apple did them in other colours as well, since the CA iD10 is silver, but that's only a minor niggle :)
"Does what it says on the tin" ordered this for my iTouch and within 3-4 days it arrived. Excitedly, I opened the wrapping and there were three perfect fits for my iTouch and dock. On the one hand it was £2.88 P&P so a total of £8.88. I think Apple should do single packs because I don't need three just one and Postage and Packing wasn't cheap
