Great ratio. Very easy to tune. Not so easy to fit if you replace tuners with screws, which was my case. Great upgrade from what I had.
Update: After roughly a year, one of the tuners just broke. Not the mechanism which is indeed smooth and with great ratio, but the little wedge that fits in the headstock. This has never happened to me before even with the flimsiest guitar tuners. I did some weird tunings, but I never tuned the A string, (of which the tuner broke) over 110 - 112 Hz of the standard tuning. Great disappointment as they work great in general. I was very lucky that it did not happen in the middle of a gig. Taylor products in general are not very reliable. Better get Harley Benton.
