Lols - you've been lucky ! Those sticks are notorious for degrading over time, and needing switch cleaner / extended periods of pre-wiggling to restore them to proper working order !
Mine had been problematic since about a year after my first flights, and eventually led to me parking the craft up and leaving the hobby for a year and half ! But just last week I felt the call to fly again, so got all my TH kit out, and went to see what was what. Batteries all good for year 3, thanks to perfect storage charge.
Rudder sluggish, and about 50% deflection, but all other controls fine. I did the switch cleaner, which seemed to fix that. However, good job I checked it again before I took off for the first of the season's field tests, because at the field yesterday I suddenly found I had zero response from Aileron input !! I did spray that one the day before too, but by the time I got to the field even full deflection of that stick would show 0 movement in the hardware monitor.
So I logged that test as fail, abandoned that session unflown, came home, switch cleaned it again, with more attention to that pot this time, and now that is fully restored to working behaviour too, so field tests can resume when it next stops drizzling !
So yes, my experience matches that of all those who have had stick issues...
OTHER issues that have been ongoing to various degrees since day 1 include:
1. Camera flickers when recording in most modes under certain light conditions. This seems to affect just me and about 3 other users though - hardly a common issue and I can't even get Yuneec to acknowledge it despite it being obvious to everyone who views the footage !.
2. The descent problem, where craft refuses to come down from a certain level without knowing specifically what to do with it when it does this.
3. The Launch problem, where the H will suddenly jump 50 ft into the air with even the slightest subtle throttle input on take-off ! Not usually problematic after that, and not a problem if you are expecting it, and possibly related to Issue 2, which itself may be possibly related to dodgy / fluctuating barometer readings.
Other than those issues though I think mine is doing rather well after 300 odd flights, and then over a year in storage. Has never crashed, nor flown-away, which is more than I can say for any DJI I have ever owned

Its motors and original props have held up to all sorts of weather, environments and still work as nicely as they did on Day 1. The Landing gear hasn't broken or stuck either, all good points in my book...
I'd say the biggest bad thing in owning a Yuneec is trying to get parts and batteries for it, which gets ever harder with every year that passes, as perhaps we might expect as product lines become this old and unsupported...
I do love my TH, and am grateful to it and Yuneec for the many happy hours of flying it has given me, but looking at the state of that company now (which I see as something like a beached whale slowly exuding its last slow sad death rattle), when it does come time to replace it it won't be with another one of theirs, a decision made many times easier now that the almighty Autel EVO 2 is officially available in the UK and comparable to the H3 in price, whilst seriously outstripping it in terms of features.
I suspect when I do get one of those my only regret will be leaving behind that 360 degree independently spinning camera, which is mainly what sold me on the TH to start with !
