You probably did the right thing. If the pink flowery thing was virtually unplayable it would probably have made her fingers hurt like hell which would have put her off playing it.
it's probably not going to help telling the mother that she bought a heap of junk either. s there no hope that the pink flowery thing could be set up to play reasonably well?
My second eldest grand daughter has just expressed an interest in learning to play guitar. So I found her a cheap entry level guitar which was going second hand for £25. When I tried it it was only just playable but a truss rod tweak, a new saddle and set of extra light strings and it plays and sounds reasonably well.
