Pretty good

for a cheap servo. Shaft slop is excessive on most but I don't use them for precision. I've had 6 and they all still work fine.

I bought 2 of these to try. Firstly they are fitted with a normal JR plug and wiring is normal.
I changed my plugs as I have a PA-09 Crimper and lots of patience. There are however adapters available if you use a FrSky VD5M Rx like I do.
Initially I put them on my servo cycler as I like to run them for 10 minutes or so before I install them. I a bit was worried as they were very jittery even on different ms settings. However when I plugged into my FrSky Rx they were very quiet and no problems at all.
They are also the first servos I have ever had that get quite hot and very quickly. I was running them at 4.8 volts. They seemed quite OK but I wouldn't fit them in anything that required some duration.
I would not buy any more of these as there are better ones available but they will suit my intended purpose at this time.

I put this little servo in an rc car that i converted from cheapie 35mhz controls to a proper rc drifter. This little servo has taken so many impacts with the wheel jamming hard over as a drive shaft popped out and yet it's still fine. Not one stripped tooth. Really an impressive servo to say the least and I would certainly buy it again for small foamies or whatever I can hack together next.

Just received 3 of these servos and checked them via my servo checker. They run smoothly and quietly, however, the centering is erratic. Basically, when at full throw either side, and you go back to neutral on the servo tester, the servo rotates back toward center but stops past center clockwise. Then over the next 10-15 seconds the servo 'steps' back toward neutral in 4-5 separate steps finally stopping near neutral. So, from my viewpoint, not usable in any situation where you are expecting reasonable centering.
