These are some good affordable tuners. I bought them because my old japanese Les Paul clone had bad, stiff tuners and they did not fulfil their function well.
When i got this product in the mail i was dissapointed because i did not look too accurate at the dimensions of the tuners (which were hard to find btw). I had to give it to a luthier to make adjustments to the headstock for them to fit, which cost me about 25 euros, so be careful with your desicion!
Now my guitar stays in tune better, tunes smooth, and i think they look good. Restringing is also made easier as you just need something like a coin to tighten up the string.
