Any updates from users? Mainly wondering if the overly enthusiastic ERG mode has been tamed, and if the slip is truly fixed? I hear slip can still be induced if doing a hard sprint
I am not able to make it slip. 
The slip is caused by the laws of physics which cannot cannot be eliminated. From what I heard, it appears at much higher wattages now, since the 2T ist stronger than all the NEOs before. 
It is just very responsive in my opinion, which is excellent for example when doing 15s/15s. The hump at the beginning of an inteval was fixed a long time ago.

Agreed with Tofel. I havenât made my 2T slip yet. I rarely made my Neo 2 slip though, since itâs relative to absolute wattage and how fast the power change was and at what cadence. It never slipped on a TR workout, only on Zwift rides. FTP is 290w @ 160lbs. though sprint power is not a strength of mine, so YMMV if you have strong anaerobic power.
I also really like a responsive trainer. I had an Elite Drivo II that was just horribly slow. Even 30/30s were difficult, let alone 15/15s. It was fine if all your intervals were longer, or you just did Zwift riding. I like to feel that âonâ and âoffâ resistance though. Outdoor MTB is a lot like that.

Agree with the above posts, I have not had any slippage on the 2T within TR workouts. Iâm a big sprinter and did not feel such when putting the pedals down hard. Youâll have to take this with a grain of salt as TR workouts and maybe Zwift or whatever app youâre using youâre always spinning at a moderate cadence before the interval.

So I guess the slip is caused more by sudden burst of 1000w from a slower flywheel speed than lets say a 400w effort and then jumping out of the saddle and putting down 1200w?
My concern is not so much for TR workouts, I know it will handle those, but I donât want slip if Iâm going up Alpe or the Radio Tower on Zwift and decide to jump out of the saddle for a bit and crank out 500-600-700w in a burst.
Iâve used a KICKR 16 for 3 1/2 years and had zero problems. Iâm passing it on to my wife and considering a NEO. No Tâs available currently but I can get the 2. Should I wait for a 2 T?
Cheers all.
Got lucky. A 2T came into stock

I think itâs the better choice from the viewpoint of responsiveness, slip and linearity (Linearity Showdown: OG vs 2 vs 2T â Tacx Faqx) Congrats on your NEO!

I got to demo a Neo2 at home and was initially impressed with Zwift performance, but not ERG. I thought it was just a 2T issue, but the Neo2 also had extremely abrupt transitions between intervals, especially doing something like vo2, it just felt like you immediately shifted 2-3 gears at a time, no ramp up at all. The wheel slip on the Neo2 was also pretty bad while seated, unacceptable while standing. Iâll give the 2T a try if I get a chance to, but until they really smooth out the ERG transitions I canât recommend either for TR use.
The same thing I thought and had the 2t for a week or two.
Iâd argue the responsiveness is a massive bonus for me. Iâve been on slow trainers and hated it. Short intervals on a slow trainer are stupid. By the time you get to desired power, the interval is almost over.
As for slipping a ton, Iâd take a look at your pedaling technique. Try to smooth out your cadence, especially while standing. If youâre pushing squares, this isnât surprising. Yes, you can get a 2 to slip (at least in Zwift with hill transitions), but unless youâre a massively powerful rider, this should not be an every ride occurrence, at least in my experience.
The 2 to 2T difference for me was extremely minor. Doing ERG workouts⌠no difference. You should never slip doing TR Erg workouts.

My average powers on those short intervals with a âslowâ trainer are still spot on, it ramps up slower (and later) and ramps down slower (and later) too. But the transitions are smooth. I just couldnât deal with that for an entire program, maybe just me
Have these issues been fixed?
Thinking of getting one but dont know reading these issues with the power
After 6 months of usage, I donât know of any issue, except that my MTB needs a simple crank arm extension for the cadence to work. But this is a technical limitation of the sensor nobody can fix and Tacx provided me with said extension.
No issues with mine either when I bought it back in November after it was released. There was 1 firmware fix for a slight issue if you used Zwift and were coasting, slight ghost power reported. I did see this but wasnât an issue for me as I use TR + Zwift and youâre always pedaling. As for the reported slippage from a few, I donât see but even if I did, it would be very minor and youâd have to be putting down some power to make it slip.
Honestly with everyone in some sort of stay-home and/or lockdown, finding a smart trainer might be tough. If youâre in California, I believe someone has posted selling theirs here on this forum just recently. Iâm glad I waited for this last generation of smart trainers especially with the 2T. I do like the simulated road/gravel feel in Zwift or other supported apps. Not quite the same in real life but still another way to add to the distraction and simulation training indoors!
How quiet is it if youâve had other trainers to compare it to?
Youâre very forgiving - I generally love my Neo 2T but the cadence sensor design is flawed ⌠I didnât pay that much money for a top end trainer to be told I have to bolt an extension to my crank for it to work properly. Iâve learned to accept now that cadence readings only make any sense for steady efforts at reasonable power - whereas if Iâm doing shorter intervals the readings are nonsense.
I am! 
But just because this is an indoor-only setup. Once the extension was installed, everything was perfect.

FWIW, I think the cadence sensor is very bike specific. It works perfectly with my Niner RLT. I have a Wahoo crank-based cadence sensor on the bike too, and the readings almost always match. Sometimes during fast cadence changes, the Neo is a couple seconds behind, but nothing major.
My first Neo 2 early last year had an issue with inaccurate cadence when they first released it, but Tacx replaced it and it was totally solid. The 2T has been the same.

This being my first smart trainer, I think itâs been very quiet! Granted acoustics in your pain-cave aka room will have some affect including the mat, how close your trainer is set to the walls, carpet, etc will make a big difference. In my pain-cave, I have the trainer sitting on a mat which is on a carpet in the dining room, near the sliding door to circulate air.
I would suggest looking at this video from GPLama to get a reference of sound but also how to quiet the trainer for maintenance.
Mine was quiet and last time I did the greasing was back early March which helps after consistent use.
