I bought one of these just over a month ago and have been so impressed I thought I would give it a mention. Very easy to use, just plug it into the I-pad (in my case) and it takes you straight to the App you need to download. Do this, pick the things you want it to control from a list (for me this was a Cyrus CDP, w4s PreAmp, Sky HD, Sony Blu-ray player & Panasonic TV), and hey-preso, it just works.
After setting up, you have an individual remote screen for each piece of equipment which you can easily scroll through, but it also has an 'activities' list which you can set-up. This is very easy to do, and I have set-up two; called 'listen to music' and 'watch DVD'.
For the Listen to Music, I have set up a single remote which the numbers & fast forward buttons control the CDP and the volume and other bottons control the PreAmp (this was the main reason I got the thing in the first place as the remote for my PreAmp is bust). Took just two minutes to set-up :-). Similar thing for the watch DVDs; volume control is set to the PreAmp, rather than the TV, and the other buttons control the Blu-ray player.
So much better than the logitech universal controllers I have tried and a lot cheaper.
Big thums-up from me.

Very disappointed with this product. Works fine on the antivirus front, but slows firefox down so much (particularly when login into or searching on things like e-bay / facebook) that I am having to turn it off while online (kind of defeats the purpose really). Great price from Amazon, but unfortunately make web browsing so painful that I will be uninstalling once I have found a suitable alternative.
