Has anyone used the RGB strips like these - http://amzn.to/15h07J3
at £17 / 5m? It seems incredibly cheap compared to the ones from mainstream dealers. e.g. the seemingly equivalent from protopic is £15 / 0.5m.
I don't quite understand why they can only be cut every 3 LEDs though, and why it says they only support 16 colours, so there must be more to it than simply RGB and ground.
I'd like to try some but wondered if anyone had any experience of them? There's hundreds similar on ebay etc.
EDIT: I think the 16 color thing might be referring to the control box, which is extra. If anyone has used these and has any advice I'd love to hear it!
