Coincidentally, after reading some posts on here I was looking at discreet cameras (I'm not keen on cycling along with a big bulky camera arm stuck to the side of my head) on amazon, saw the Muvi and decided to see what people on here thought. So, it's likely you're all going to be responsible for my £90 (including accessories) impulse fork out!
Thanks for the youtube footage. That really helped seeing what it does and how it does it. Also thanks for the tip on the Class 6 card.
My mouse button still regularly hovers over the "Proceed to checkout" button, but I'm sure it won't be long until gravity does it's thing and the camera is on it's way to me! £54.51 with free postage for the camera is outstanding!
