This is a great speaker set, the sound is fantastic and it's so compact it's just great to use around the house or take camping.
A few criticisms though, the remote control has to be pointed directly at it unlike other remote controlled devices, which can inhibit where you position it.
In order to use it as an aux speaker using the 3mm jack, you have to have the source (laptop, mp3 player etc) on full volume or the speaker will keep turning off, this doesn't affect the brilliant sound quality but the speaker comes on at a really high volume, and I'm worried one day I might set it up and go make a brew or something and the speakers will blow.. Plus, it can give you quite a shock!!
Even though it's marked to 'Work with iPhone', I still get that stupid message on my iphone when I dock it warning the product isn't designed for iPhone, however, I just discard it and I don't get any interference, even when I use the dock to listen to internet radio through the iPhone's 3G connection.
All in all, a great speaker that pumps out brilliant sound that can compete with a lively party, despite its small size, which in turn makes it a great companion on a camping trip or BBQ. Knocked a star off for the mild annoyances it delivers as it is a pricey product and you'd expect it to be perfect. There are cheaper portable docks out there, but you will be compromising on sound quality so it's worth saving up for this fella and being happy with it!
*Quick Update* - Forgot to mention in my original review that the speaker comes with plug adaptors or the UK or Europe. Went to Prague for the weekend so took the dock with me and cracked out the Euro adaptor which meant we could have a great soundtrack for the weekend in our apartment and I could also keep my iphone charged up without having to mess around with adaptors for the charger. Only took a small rucksack as hand luggage and this speaker hardly took up any space. Another plus point! Not quite enough to win that fifth star though..
