Daddario PWAT-331L

First the good:
- Quality seems okay. Not the most robust tuners I have, but quality is good.
- The automated cutting of the string is a weirdly enjoyable experience.
- Changing strings takes even less time than with normal locking tuners.
- Tuning ratio is okay-ish. I prefer a more precise ratio than this, but it's very usable.
- They stay in tune really well! Even with new strings, it's very stable.

And then the bad:
- The screws that were in the package are of extremely low quality. On one of the screws, the head broke of while the screw wasn't even full in yet. So now there is a metal pin stuck in the wood that I have to drill out someway... That will almost be impossible to do without making further damage to the guitar. It didn't break my guitar or anything, but it certainly did damage and took something of the resell value. I would never use these screws again. They felt bad out of the package, but unfortunately they lived up to that expectation :(.

I own an ibanez ajd71t that comes with a floating Gibraltar bridge. I loved this guitar from the start because it looked cool and all that but unfortunately it would never stay in tune.
With that said I eventually put it aside and only picked up that guitar on a rare occasion because it got a little frustrating.
So I decided to pick up these tuners and they gave it a great new lease of life.
They're reasonably priced and the quality you get for the price is more than pleasing.
I fit them myself because I do a lot of guitar repairs and I can honestly say that I don't imagine anyone should have much trouble adding these to their own guitars.
They fit well without any other adjustments and after a quick restringing sessions I was ready to start playing my guitar again.
I found the restringing procedure is reduced in time considerably because you're only winding the bare minimum of string that you require and it holds its tuning admirably after the usual stretching of the strings.

I plan on adding these to the rest of my guitars that don't have locking nuts because it's reassuring to know that I won't have to worry about the strings suddenly going out of tune mid song when I'm doing some aggressive bending.

They look great too, the materials appear to be sturdy and I haven't seen any tarnishing or blemishing of their appearance since I installed them.

So to conclude, these tuners are high quality, they look great and they do their job as well as I could have expected. Worth your time if you want to sort out that tuning instability on a guitar that you know could be great with such a simple modification as this.
