  1. what are they thinking ? i’m trying to be nice here but i strongly advise they go back to the drawing board .
    i would not even buy this product for a £1.00 at a car boot sale.

    maybe if it had a screen and some foot pedals lower down it would be more usable ,but to have to slot card/paper in.
    what if each song in your set needed different ones inserted ??
    i’m very confused as to why no-one close to them has told them the truth.
