Ok I found my list, my camera is working & I have a few minutes to spare so here is number 7!
7Time Lord Psychic Container
When these were first announced I wanted one straightaway, but it proved tricky to get one that didn't have the mark of the Corsair on it. I really liked the one with the Gallifreyan symbols so I held out & eventually got my reward.
In case you don't know what it does - it lights up when you tap it in one of 3 modes: static white light, flashing white light & colour change.
Here's a pic of it on one of its colours:
As well as looking very cool on the shelf, I have found this useful when we have had power cuts, just as a little extra light - it actually throws off more light than you'd expect. You couldn't read by it, but you can find stuff & stop yourself falling over something that you've forgotten on the floor.
One that I got because it looked cool, but as it turns out it fulfills my practical requirements too, Double win
