I use the product for guitar maintenance and upkeep
Overall I believe this is a good purchase for the price considering the majority of items in the set are a one time buy unless you lose them. The polish is quite good and gets the job done, but very very surprisingly the picks of all things (which I originally didn't even realise was in the set ??) are my favourite picks that I now own. However the box that the set of screws came in is not very well made at all and broke during the shipping, however the screws themselves are fine. I use the items all the time and would recommend to any guitar player who doesn't have any (to all the two you) to absolutely go and purchase one.
