I.M.O.
I have been going for the last 6-7 years.
Its changed venues a few times, and this year its near Caerwys,
The price had gone up to £15 and wasnt really worth it, has it hadnt really improved at all, however the price has come down this year to £12.
I herd lots and lots of bad reports about it, to the point it was canceled at one point, but seems to of over come it and this year its on.

For £12 its probably worth the locals going for a look.
But all that said Its just my opinion and I wouldnt want to put anybody off going.
If its your thing and if you havent been before I would say give it a go.
