This product is good. Great, even, given the price.
I have an old Yamaha guitar which I accidentally bought from Japan. It had only four tuning keys and four saddles on the bridge. I thought - well, my sight is pulling tricks on me, I thought this guitar is complete. Good thing it itself cost around 10€, but the import was a real pain. Never mind, I turned to Thomann and HB for parts for my accidentally purchased guitar. No regrets.
