Göldo Zero Glide ZGZS1 Nut

The slot distance of between the 1st and 2nd strings is rather off by nearly a millimetre (around 0.75). I compared it to the original nut of my Gibson Midtown Custom. At first, I thought this is not a big deal but after playing for a few days I realised it's not at all a nice feeling. The first string slips out of the fretboard more easily. I don't mean at all that is impossible to play if you have proper technique but definitely the slots on this nut do not come with the quality standard you're likely to have with the original nut.

For the rest, the overall sound it's just insane. You'll lower your action without buzzing, in some ES and Les Pauls the intonation will definitely improve, and the sound of open strings will get richer.

Great but... Mind the gaps.
