They were really popular when I was at school and I used to be able to solve in under a minute on most attempts.
Lucky if I remember how to solve it in under ten mins now, but in some cases I can only solve a layer if I don't think about it too much. My subconscious knows the moves, but I don't!
Once spent hours walking round a french campsite on holiday with my cousin saying 'Quelle couleur?' to ask which side to solve first. We must have solved every cube on site by the end of the day!
A place to discuss anything.
I tell ya what also!!! My manual trading has improved!!
